I'm not 'on' about anything. GC was actually asked about this on Twitter I believe, someone asked if it was a bug that Dragon Roar didn't proc Bloodbath, or intentional, and he replied that it was intentional, citing the 'always crits/ignores armor' as the reason.
Maybe its a decision they quickly undid/backed off of, but the Lead Systems designer of the game said it didn't and gave reasons for it. So, I assumed it didn't. :P
Though I've noticed that it's always just dps up to hit it even on single target, what shouldn't be right (well, according to sims at least). However a long cooldown should still make it always a "bad choice" when you can always take big hitting dragon roar obviously.
Though hell I always do more dps with stormbolt on Arms and simcraft still sims bloodbath to be like +3k more dps, so I guess nothing is ever 100% accurate for sims. =P
Also I don't know how simcraft is supposed to even sim up stuff like how many stacks my gaze of twins give, since I replace overpowers with slam purely if colossus keeps proccing and I have at least 2 stacks on my crit trinket (and rage allows it). At least personally I get way better dps results to purely hit slams and skip OP during colossus when I have over 40% crit chance on it. That trinket might also contribute to more stormbolt crits though.
What's happened to this class? Why is it ok for this class to loose all it's "UMPH"? I remember a time when "stop feeding the warrior rage because we're all gonna die" was something everyone thought when fighting against a group with a warrior.
I liked having abilities that greatly increase the class's potency and power for short periods of time like recklessness and the now removed retaliation. Recklessness is now just a former shadow of itself and this guy is thinking of completely removing it. Because making it 10% is like removing it, but 2 patches later, just like deadly calm was nerfed to bits and then removed.
I used to PvP a lot during TBC. Thinking back on it now, it's a bit weird, because my recollection is that there was a lot less burst, especially in 2s and 3s, even WITH heroism/bloodlust, and old recklessness etc., my general memory of the time was that we outlasted our opponents mana bars in mirrors, and kept high constant pressure up on them until they made a mistake (e.g. your healer managed to kite one of their DPS out of LoS and on about 50%, quick CC + switch and kill him).
Edit: I should also say that I did once manage to one-shot a mage at 2200+ rating on my Warrior. I got a multi sword spec proc on a Mortal Strike crit, must have been about 4 procs or something, and it just insta-gibbed him. That was back in season 1 before sword spec and mace spec got nerfed (justifiably!).
