yes, this would make a good hunter weapon, but
all that hunters really look at is the stats on it, and a good hunter almost never melees, where as a ret pally or warrior, all they do is melee, making it more useful for melee classes.
570 top end damage is amazing for a 2H weapon, and it kills me to think that some hunter would be putting that to waste when a warrior could be using that every fight. as for your arguments that MS warriors are totally useless in raids, you are incorrect. like was stated before, they have the debuff that increases all physical damage taken by the target by 4%. on top of that, if you put them in a group with other warriors, they can stack shouts, and depending on the way they have specced (MS / fury so they have commanding presence), their shouts would be more effective than that of a purely prot specced warrior, which apparently is the spec everybody thinks that every warrior should be, despite the fact that MS and fury warriors make some of the best damage dealing classes in the game. or maybe, you  all do realize that and are  just jealous of that and possibly embarrased when you see that you are lower on the damage charts, so you all cry and say "nerf warriors to tanks blizz." in my opinion i think it is a load of bullshit when people say warriors aren't supposed to do dps, and the people who do say that are either

a) people who can't move past pre BC when all warriors did was tank

or

b) disgruntled players who are mad at the fact that they have inferior dps than the warriors arond them

anyway, i think it's a great weapon, and congradulations to whoever gets it


and that ends my ranting session for the day
