There are going to be two accepted raid specs for 25 mans as of right now, we may add an Arms warrior once we see that you can do a decent slam rotation and generally don't suck too bad.
Prot:
there are a few different ones, each have their own benefits

should always have one of the OTs speced like this, this adds the most mitigation debuffs to a mob, and still almost has the same amount points in prot.

This one is nice for trash and heroics. adds alot of CC and interupts to what you can do as a tank. I <3 this spec for heroics.
Fury Spec

this one covers the debuffs for your tank and is close to your max DPS. There are several variations on this build, but something like this should be used.
Any questions or comments or discussion post on here, or PST me in game Smile
