in my opinion, if they were to bring more of a focus to the 2v2 bracket back into the game it would be much more fun on a consistent basis. much like skirmishes, the 2's bracket being fun allowed people to just log on and have fun almost all the time. now the focus has shifted to 3's, which can at times be difficult to have people all on at the same time for. gradually, even the focus on 3's is being shifted to RBGs at least from blizzard's perspective. "2's isnt balanced." of course it is not, and neither is 3's. it's just that the more people that are in the arena the less noticeable classes balance issues are and the easier they are to overcome.
IIRC health pools were around 10-12k. tho warriors could often reach higher. i played a rogue and warrior in TBC(warrior in s3/4). you didn't need deathwish to kill people, unless you wanted to kill them right out of the gates when both teams had full cds. at that time, however, the game was more about the opposing healer's mana OR reflecting a cyclone/shatter/poly etc. it wasn't the best system, having extremely long drink-fest games, but in my opinion it was much better than "pump dmg with cds or you cant kill anything" mentality that it is right now.
That 2v2 part really got me - I miss 2v2 so much
