Just curious, why are you benching your warrior? I have my own problems with the prot spec, so I'm enjoying bear more now. But don't think I'll stop playing him.
Honestly, I just don't enjoy it. My DPS on Mythic Nythendra for instance can swing about 50-70k depending on Tactician procs. Throw in a poorly timed rot debuff or two and I am practically useless. Fury is just, it's just underwhelming. The rotation is ok (although keeping up a 3 second enrage buff is annoying), it's just very underwhelming. I enjoyed Arms prior to the 30% nerf to Focused Rage & the normalization of Tactician procs. I decided to hold off until I received my first legendary, just to see if maybe I scored the dps ring or even better the Archavon gloves. Sadly I got the neck.
Focused Rage doesn't even get used other than rage dump and in Battle Cry windows now, yet you still must take a talent that makes no sense now that the priority has been nerfed down. It's just a shitty class right now. We entered the expansion with four warriors, one with three legendaries. We now have zero in our active rotation (druid, hunter, mage & whatever I decide to play). Prot was solid from what I have played, I know the tuning to vengeance turned off one of our main tanks enough to go druid, but its still very serviceable.
I applaud people for still playing it, it just feels really boring now. That's never been a complaint I have had about the class, but guess now is the time. Not to mention, the hotfix today for the Arms hidden artifact was icing on the cake. Claim all the triggers are in the game, players are looking all over spending countless hours. "Whoops, we didn't add it into the game". They've really struck out in their handling of at least that class.
Ps. I am leaning mage. My thought process is that with three dps specs, surely at least one will always be strong dps/entertaining enough.
