Demon hunter as new class possible?

Hello there fellow lore lovers.

I must say that World of warcraft already offered alot of lore... but still there are lots of missing puzzles about Demon hunter class.

First Some lore from .
http://www.wowwiki.com/Demon_hunter

Demon Hunters are dark, shadowy warriors who are shunned by greater society. They made a pact, long ago, to fight against the forces of chaos using its own terrible powers against it. These mysterious warriors ritually blind themselves so that they develop 'spectral sight' that enables them to see demons and undead with greater clarity. They wield demonically charged warblades in battle and even call upon demonic energies to augment their formidable combat skills. Although they are counted as some of the mightiest warriors within the night elves' society, the demon hunters are always maligned and misunderstood for making their selfless pact with darkness.WC3MP 56 Though many among the night elves and the Alliance fear the demon hunters and their pact with darkness, all know that demon hunters and their demonically-charged warblades have played an important part in combating what remains of the Burning Legion.[1]

Background
Illidan Stormrage is the most famous demon hunter, and was the first of their kind. Even Illidan's own brother did not appreciate his sacrifice, and locked him below ground for thousands of years for trafficking with dark powers. Illidan's case was unique. Sargeras, lord of the Burning Legion, burned away Illidan's eyes with magic fire until only scorched sockets remained. Illidan's resulting sight was a maddening display of violent colors. His altered vision allowed him to easily recognize both demons and mortals with magic powers. In addition, Sargeras covered Illidan's body with black tattoos that increased his arcane power.[2]
Later, a group of night elves, inspired by Illidan's example, made a pact to turn the Burning Legion's powers against it, fighting destruction with destruction. Obviously they could not gain their powers in the same way Illidan did, but they discovered other means. In the millennia since, other night elves, and a few creatures of other races, have made the same pact, binding demonic essence in their bodies and using it to destroy the Legion's minions.[2]

Development & abilities
Demon Hunters have a variety of abilities that assist them in destroying demons, though the power coursing through their bodies also allows them to prevail over lesser foes. Demon hunters eschew heavy armor, valuing mobility and speed. As a demon hunter grows in power, they undergo a gradual evolution, becoming more and more demonic in appearance. The changes are cosmetic and can take many different forms, from burning eyes to black blood. By the time the demon hunter reaches the pinnacle of his development, he is a twisted and dark version of his former self - though the chaotic energy in his body does not affect his personality and allegiance (or so the demon hunters claim), it wreaks great changes on his physical form. The demon hunter’s gradual evolution achieves its pinnacle as they become a demonic entity. Their appearance has changed to something frightening: The exact changes vary, but can include glowing red eyes; horns; clawed feet and hands; nonfunctioning wings; cloven hooves; a spiked tail; dark skin; a deep, rumbling voice; and similar cosmetic changes. The demon hunter becomes an outsider.
The demon hunter can drain a demon’s energy to fuel their own powers. They mainly use arcane and fire energy. Shadow energy is rare. No other energies have been confirmed. The demon hunter can channel the chaos energy within them into a melee weapon to increase its powers. In time the demon hunter becomes more proficient in channeling demonic energy into their weapons, and highly skilled demon hunters are adept at this technique. Demon hunters have shown the ability to cover their bodies in a shell of flame. At the pinnacle of evolution, Demon hunters can unleash the demon in them and turn themselves (temporarily) into something more. This is called Metamorphosis.

Weaponry
To contrast their stark lack of armor and clothing in general, demon hunters seem to typically carry large, curved warglaives, in the style of Illidan Stormrage's own Twin Blades of Azzinoth. Though the exact reason for this tendency isn't well explained, there are several possible reasons. One is that this kind of weapon has simply become a tradition over the years, later demon hunters mimicking the first of their kind. Another is that this style of curved warblades is common among the kind of demons that demon hunters have to kill as part of their basic initiation process. A third explanation is that the dual-bladed nature of their large, curved weapons allows them to deal the most damage with the least amount of effort, allowing them to focus on their agility and speed. A final explanation is that this kind of weapon is somehow easier to magically charge or channel through, though there is nothing that directly suggests this.
Demon hunters also possess a plethora of magical abilities, most notably the ability to metamorphose. Many abilities also tend to vary from demon hunter to demon hunter, possibly derived from the type of demon that they originally partially absorbed.

A demon hunter warblade.
Demon hunter warblades description: These blades appear as a strange cross between a small buckler and a sharp-looking, curved, two-bladed short sword. The demon hunters of the night elves wear these blades while they hunt the minions of the Scourge, the Burning Legion or other dark adversaries worthy of such weaponry. While many of the demon hunters rely on non-magic weapons, eventually most have either one of these double blades or a matching pair.[4]
The use of such weapons tells a lot about the individual wielding them. The inwardly-curving nature of the blades means that the demon hunter must get extremely close to their opponent, literally within what would normally be punching range, in order to get maximum use of the blades. The warblades would be swung in wide arcs at extreme speed, viciously lacerating the foe. More often than not, the warblades will have intricate serrations on the outer edge of the blade near the central buckle, adding yet another facet to the brutal nature of the weapons.

This is known about them and this is great chance to open one question about Glaives in game. I mean every guard in darnassus has it why cant we use one as melee. Only usable glaives are Warglaives of Azzinoth. Where are other similiar models?

We also have some Demon hunter's in game already.
Naturally, Illidan Stormrage is the most prominent demon hunter currently residing inside World of Warcraft, but there are several others of note.

Loramus Thalipedes resides in Azshara. He directs the player to the true name of Razelikh the Defiler, and crafts a piece of enchanted azsharite weaponry that can slay him and his minions.
Vish Kozus (unconfirmed) located in Cenarion Hold in Silithus. He is only the quest-ender for a small handful of quests, and no backstory is available on him. However, he wears a blindfold and dual-wields two long, curved sabres.
In The Burning Crusade

This section concerns content exclusive to The Burning Crusade.

Theras, Netharel, and Alandien are night elf demon hunters brought to Outland by Illidan, and are training the apprentices at the Ruins of Karabor.
Altruis the Sufferer is a night elf demon hunter who also accompanied Illidan to Outland, but later defected. He can be found battling the Burning Legion in Nagrand.

Varedis is also found at the Ruins of Karabor. Of the first five blood elves to be trained by Illidan, he was the only one to survive with his sanity intact. He is now in charge of training additional blood elf demon hunters.

Leotheras the Blind, who dwells in Coilfang Reservoir, was one of two blood elf demon hunters to be trained by Illidan and survive. His sanity, however, did not.
Inside and around the Black Temple are quite a number of apprentice blood elven demon hunters.

In Cataclysm
This section concerns content exclusive to Cataclysm.
Feronas Sindweller resides at Felwood, where he kills demons disguised as druids.
Telarius Voidstrider, the Herald of the Dark Embrace, whose ghost resides inside Bashal'Aran Collapse beneath the Maw of the Void.
Loramus Thalipedes, initially found dead (in several pieces), is resurrected through a quest chain involving getting his body parts from Dreadmaul Ogre lockers and resurrecting him at the Altar of Storms in Blasted Lands. Rather than have to travel to Azshara to complete the "You are Rakh'Likh, Demon" quest line, he is conveniently located in Blasted Lands for both Alliance and Horde. The Cataclysm quest line is slightly different to the classic quest line.

So i am giving this Question to Blizzard Developers. Is it possible to expect Demon hunter class in game?
