First off, this week's PTR news: basically, nothing new from the last time we talked about it. Arms warriors can pick up Juggernaut now. It's fun. I'm already sick of the macros I'm seeing with it, although I haven't had that much time to do more than charge and then Bladestorm a few mobs just for the laughs. As soon as I get a chance to PvP with the changes I'll tell you if the caster debuff on Overpower from Unrelenting Assault makes any difference.
I get a fair amount of email asking me what target numbers a warrior should be aiming for when he hits 80 and is ready to tank or DPS in instances. It's kind of a hard question because for some stats the best answer is always going to be "as much as you can get" - you're never going to hit a number on stamina where you should be satisfied, you'll always want more and more and more of it. However, there are reasonable suggested minimums for these things, based around what will be possible or impossible to accomplish. A lot of this depends on the folks you find yourself running with, of course. If you're just starting heroics but the healer you'll be running with has best in slot raid epics from all the 25 man content in the game, it's likely he'll trivialize the content to such a degree that you can be significantly lower than normal and still do fine. For those of us who don't have a pocket god coming along to heal our runs, however, you may have to pay attention more to your gearing.
