Alright gonna preface this, with I am completely stoked about Cata regardless of what lore they tear to shreds, because the gameplay changes look sick and I'm hopelessly addicted anyway.
But still the inner lore-nerd in me is just outraged at some of the new race/class combos they are allowing. So far, I've heard their logic (excuses) for Tauren Paladins, so I'll just accept that and let that be. But some of the others...I can't wait to see what kind of rabbit they are gonna pull out of their hat to justify them.
Worgen Druid? So we have a kingdom of xenophobic humans who have been cut off from the rest of the world for generations, and have been transformed into a race of werewolves. So they once were friendly with Night Elves so this means they can be druids now? What about the humans, dwarves and gnomes who have been fighting alongside the Night Elves all this time the Were-men were hiding behind the greymane wall?
Goblin Shaman? This one really gets me. Goblins are supposed to be this plundering, greedy, money-driven race. How on earth they can then turn around, and befriend the elemental spirits to gain their blessings to use their power is beyond me.
Undead Hunter... yeah so all this time there was one human hunter who was taught the ways of communing with nature in order to tame beasts and be a ranger warrior. Now all of a sudden the undead humans, who have done nothing but shun anything in nature unless trying to pervert it via alchemy now can manage to master those abilities?
Nelf Mage: Ok so an entire society is splintered, the world itself is nearly ended in an apocalyptic sundering, and a portion of their wayward brethren now roam the northern region of the eastern continent crazed and starved to fulfill their addiction to magic. And they are going to just forget that, turn away from their druidic-based society and re-embrace the magic that nearly destroyed them twice over? Some things in this game gave it flavor in the form of contrast. Having mages in the alliance while despised by the night elves was one of them. Though I suppose if orcs can be warlocks, then nelves can be mages >.>
I'm all for most of the class combo changes, but these ones are just beyond me. I can't wait to see Blizz explain them away -_-
