Before we even get started, yes, that is a warrior in Tier 1 with a Terestrian's Stranglestaff equipped. For some odd reason the staff only drops if we have no druids on the run, so there you go. Why is he in Tier 1? Because Tier 1 still looks freaking awesome, that's why. And that's not the lookalike 70 blues, man, that's the old school set. You can tell by the coloring. (You know you've been playing a warrior for a very long time when you can look at a piece of gear and know by its color what it is.)
I've talked a lot about how I mostly tank nowadays, so it's kind of ironic that I'm talking about DPS today, considering that I mainly DPS'd for months and months and seemed always to be talking about tanking. Maybe I should start running around bandaging people. Or I could make a whole lot of food before the raid and pass it out to folks while making weird gestures beforehand.
Anyway, warriors as DPS are, as always, melee. We don't have much in the way of spell damage (no, Thunderclap doesn't count) and even our debuffs generally make for up close action. Basically, all warriors (be they tanks or DPS) hit and yell at things. That's about all we do, really, we hit things and we yell at them, either making them feel bad (Demoralising Shout) or good (Battle and Commanding Shout), and sometimes we break wind so powerfully that they can't attack us as fast (Thunderclap). Okay, so the tooltip doesn't actually say that we're flatulent when we use Thunderclap, but I've yet to see any other explanation as to why I can explode periodically for physical damage when I have no magic. Yes, it counts as a spell, and yes, it's mitigated by armor, so I'm totally in the dark as to what else it could possibly be.
The Care and Feeding of Warriors may just have had its first fart joke. I'm sure we're all very proud. Now that we've all gotten that out of our system, so to speak, let's get on to what a warrior DPSing is and isn't, and what they can and can't do. I'm not going to dwell too much on things like weapon speed or if dual wielding is superior to a 2h weapon because that will really ultimately depend on your build, and I won't know what that is. There are DPS builds in both arms and fury that use 2h weapons and dual wielding (although I have to admit that I don't understand a dual wielding DPS arms build very well) so such a talent choice will be up to you.
