I don't know much about warrior except they wear big armors and have big weaponses.  Although being on the receiving end of the beatdown on more than one occasion I know that as a healer I really hated that MS debuff.  I dunno why everyone has gone fury recently cause when I read the warrior changes I don't know what half the abilities do exactly so it sounds foreign.

I do know that MS debuff is a pretty unique debuff and can beat the tar outta a lot of people.

I've got no clue what is best for grinding.  Maybe tell us how you see each one working out and people can chime in with what they know.  Is one spec more gear dependant than another?

Not sure how the rage normalization has affected you, but what spec is more known for putting out higher consistant dps rather than the huge burst dps? I'd say that one is better for grinding
