It’s hard to say whether Blizzard has ever been, or will ever be, happy with the Talent system in World of Warcraft, but it has been relentlessly reworked and reinvented since the game’s launch. While there are many reasons behind these changes, and in many ways they are expected in a MMORPG, not everyone likes the outcome. Hold onto your hats, because the most sweeping changes we’ve seen yet will arrive with Mists of Pandaria, the upcoming expansion, and it has already provoked heated discussion in the WoW community.
The idea behind the Talent system is to give players a way to customize their character’s abilities within their class. Without Talents, the abilities your character has would be practically identical to everyone else in your class at that level. Although there are several other ways to customize your character, the actual skill sets within a class would not vary much, if at all.
