I've done a bit of ZA on my warrior as Fury. I can't say I raid that way as much as I'd like to, but I didn't notice a buff or a nerf to overall DPS. I still pulled aggro on trash.
The Bear boss was where I had my biggest problems. I was able to DPS my heart out, next to another rogue, not quite as well geared as I was. I got behind in DPS at a point, and really ramped it up with str pots and trinkets and stuff, but never really had the Umph to bring me back on par with tanks that were taunt catapulting their threat above the rest of the raid.
The rogue and I were soundly over everyone else's DPS, but he still beat me out, I'm pretty confident with deathwish I'd have been able to ride the aggro curve alot more steadily than I did in that fight, and as it stands I wasn't as close to the MT in threat as I'd have liked to have been, which is a big nono for fury warriors. On the bright side, maybe I won't die quite as often.
Some things to account for, we hadn't done bear boss very many times at all, so no one was really comfortable with the fight. I did have salvation. I may not have had the perfect fury talent spec, but it wasn't bad, still a 17/44.
Maybe I'll do some testing on the invincible guys today in blasted lands, a 3 minute test with the same gear popping trinkets and cooldowns. I won't go so far as to count how many individual bloodthirsts and whatnot I do, but I'm pretty consistent with my damage rotations so it should be fairly accurate. (Maybe I will keep track, shouldn't be too hard with SW stats)
