Design for Dragonwrath, Tarecgosa's Rest

We have seen a number of questions about the legendary weapon Dragonwrath, Tarecgosa’s Rest in patch 4.2 and how it will work for some classes and specs. Basically, the design was to make this legendary appeal to any damage dealing caster, without it being of greater benefit to a specific class or spec.

To help with this intent, the Wrath of Tarecgosa proc (which duplicates harmful spells) will also apply to damage over time spells, with a chance of duplicating each tick from a DoT spell. To further ensure the weapon is of interest to warlocks and Shadow priests, the proc has no internal cooldown and the proc chance is adjusted favourably for specs that derive a significant portion of their DPS from pets.
