I decided today that Zul'Drak is my favorite Wrath zone. The beginning can lag a little bit, but once you get to the second level of the kingdom, it really heats up. It feels like it really was a kingdom once -- not a castle or a village, but a real kingdom where trolls lived and died. The whole place feels foreboding and formidable -- even the trees look mean. And when you get there, it's completely screwed. You travel up the tiers fighting Scourge, and then suddenly: holy crap! The trolls won! But how did they...oh. Well that's not very good.
The atmosphere is nearly unmatched in the rest of the game. It's bleak for so many reasons. The bottom is bleak because the Scourge gained too much of a foothold. The middle tier is bleak because you understand what the trolls did to win. And the top tier is bleak because you realize no matter what, the Drakkari are doomed. The enemy is dead, but the empire is dead ... and the gods are dead.
If they make a Bard class will it wear Int/ Mail since there are so many others fighting for plate and leather gear?
It would make sense from a gameplay perspective, though maybe not necessarily from a flavor one. Bards tend to be lightly armored, and mail is the second-heaviest armor. Then again, WoW doesn't have any bards, so there's nothing in the canon to base their armor class on!
