Balnce you mean you guys actually balance this game thats the first i heard of this. Right now we will hear how you are trying to balance the new expansion. I will bet my life on it that the monks and the new cuddly utterly hateable pandas will be either so weak or way over powered. Your developers never seem to get it right when it comes to balance.
Let's get one thing straight here. World of Warcraft (and all MMOs) are in a constant state of being balanced and tweaked. As more content or more game changes are added, so too must additional balancing be done. There is no such thing as a "finished" MMO. That is the nature of them. Balance, is an ongoing work. Also, what you may think is "right" may not be either. It's pretty easy to sit on the other side of the fence and say, "Get it right!" But there are so many variables at play that it's never that simple.
Also, it seems there are several discussions going on here. My comments have been directed at Heroic Dungeons and dungeons in general. I wasn't commenting on Dragon Soul.
In regard to Dragon Soul: I work on a global community report each week in which every week I see a mix of people that are upset about the buff, and those that are thankful for the buff so that they can progress. It's not a black and white issue. We did something similar in Wrath of the Lich King and we changed it again for Dragon Soul. Who knows what we'll do in future raids.
Yes, people can experience the Raid with the Raid Finder, but that doesn't mean their guild isn't interested in accomplishing the Raid together either. I think there is also an assumption that "everyone has seen it/done it" and that's not exactly true either.
As to whether or not we will "nerf" Challenge Modes, I couldn't say. I can say we will balance the dungeons that they occur in. But they are intended to be very challenging for organized groups. There is no Challenge Mode Finder by which you can make a new group and go in with strangers.
I see a lot of people upset about how this hurts their own experiences. How by making it too easy, you're getting people who may not fully understand the mechanics of some of the encounters or may not play at the top of their game. On the flip side, if only a small portion of people can get through that content, it gives you a very very limited pool of folks to be able to play with.
Again, we're not in a black and white situation here.
That all said, /broken record on-
We are always open to constructive feedback on how you think the system could work better. No one on our side has packed up a suitcase and walked out of the studio because their work is "done". We have a large team of folks who have been working their tails off to get the next expansion ready and out to you. They have been reading over the forums, listening to the community team, reading outside the forums, and still putting in their time to work on a variety of thoughts and ideas whether they came from without or within.
Will things potentially be "out of balance" with the release of Mists of Pandaria? It's possible. Beta can only tell us so much. Even with such a large pool of people taking part, there is always a difference when it comes to the live environment. The developers do the best they can to make sure the choices they make are for the betterment of the game.
Back to the topic at hand, we're back to the simplicity of the original statement I made-- Challenging is different for everyone.
I would also caution people to avoid these statements, "If only Blizzard had had their eyes open and brains engaged." This is not thoughtful or helpful in any way shape or form, nor is it constructive. If the developers don't agree with your ideas, that does not mean they don't have their "eyes or brains engaged".
