Firstly, please don't consider Darzk's build. I actually play a warrior in this bracket and I can say that his build is a bad idea.
First things first, 2H arms is the best spec in this bracket for warriors, don't let anyone tell you different.
However, I have had alot of fun with my imperfect dual wield spec, and I def recommend trying it as it's hilarious seeing your one handed sword shit on people for 400 heroic strikes.
Secondly, roll Orc, they're funner.
On to the build!
chardev.org v6 ~ a World of Warcraft character planner This is THE dual wield build, included spec and glyph.
Let me explain why you want to gear like this should you choose to go DW,
the spec is 12/0/8, why? because arms gives you 5 percent perry, improved rend, 1 point in tactical mastery (for disarms and shield bashes and such) , improved charge (this is key) and impale,
The 8 points in prot are for improved tclap, (filler, really, although nice overall for 3 talent points) improved Bloodrage (also key) and incite, the whole reason for speccing into prot.
This build focuses on Heroic strike, so you have improved charge and improved bloodrage to build a ton of rage, and white hits which also build a ton of rage. this build has a 30 percent plus crit chance on heroic strike, also, heroic strike doesn't get penalized by the dual wield hit penalty.
The gear is the way it is because warriors need the hp, they just, do. DMH is a must, don't listen to anyone who suggests otherwise, this thing is amazing for warriors.
as a DW warrior you want to use a fast offhand, because without taste for blood you have to rely on dodges and parries (the build major glyphs overpower) and a fast offhand yields more dodges and parries because it its more often, giving you more op's.
A basic rotation that you wanna do for this spec is charge, blood fury, hamstring, rend, sunder armour until you get a crusader proc, then whore a bunch of rage , wait for an op and unleash a chain of heroic strikes. this will do a ton of damage because my heroic strikes (without even perfect gear) easily hit for 450 with sader up. it's really fun to watch chains of heroic strike crits when they happen. (got in the high 500s with orc racial up)
But yeah, I'll say again, this spec isn't the overall best 29 warrior spec, although it's very fun and if you're set on makin' it, go for it and have fun.
