AS a couple of people have stated, MS warrior's are really good in 1 vs. 1 PvP. I like the fact that MS warrior's deals a pretty good load of damage, and with that amount of armor that warriors have / will have at level 70, they will be able to reduce a pretty good amount of damage from other classes. Talking about melee / ranged damage now. When it comes to casters vs. warriors, there is basic things to think about...

Vs /priest's / warlocks: Berserker stance for fear resistance.

Vs. Mages: Here is hamstring really nessesary, 'cause if it's a frost mage, they'll just slow you and play with you. even though fire mages will be able to run around with you like f you where their tail too...

Vs. Rogues: Thunder Clap might be usefull, since it lowers their attack speed...

Vs. Shamans: Hmm, never thought abut fighting these suckers.. They mostly turn up in resto specc, and just stay feeted and heal them self...

Vs. Paladins: If these loladins/bubbledins shield their self, remebmber to use a little bandage aid.

Vs. Hunters: Slow 'em down, since their melee ability's aren't even close to the warrior ability's.

I don't think you all will agree with this, but this is atleast my point of view.
