I like tanking on my warrior, sometimes I don't enjoy that other classes have an easier time solo tanking certain fights due to their cooldown setup. Overall I think any gimps in the class can definitely be overcome by skill, such as single and aoe threat.
The only other 85 I have is a hunter, which just dinged the other day. Over 6 years playing this is my only other max level character. He is fun in the following ways: Keeping the slow random group moving by MD pulling to the tank. Being unable to be kicked for that reason due to keeping the group in combat (getting yelled at for it too). At the same time, topping dps on every fight and trash pull and finally at the end no one can stay upset because the place got cleared 3 times as fast as if I let the tank stand around before every pull.
