You know, I really like the way the warrior tank plays in Wrath. At least at level 66, which is where my lowbie tank has gotten to.
There are two major things I like about warrior tanking. First is Charge. Warbringer is one of the best talents in the game. Charging into combat is fun. Charging around during combat is fun. Charging into the next pack when the current pack is almost dead is extremely fun.
The second thing is Thunderclap and Shockwave. The thing about these skills that I like is that they very much reward you for timing things well. There's a satisfaction from Thunderclapping at the exact right time to get every mob in the group. Or lining up the perfect Shockwave and stunning everything just right.
It's not like Thunderclap and Shockwave are hard to use. But you can make mistakes with them. And that makes using them correctly valuable.
All in all, I really like the way the warrior tank plays in Wrath. I hope it doesn't change too much in Cataclysm.
