Oh yea, I don't think this was covered but ms has been a house for a while. The easiest way to compare it is to a hunter. If you want to get a general idea of how it scales think about how hunters weave steadyshot and multi shot between there auto shot. OK, now do that with your slam and ww cooldowns, a ms warrior can easily be in top the dps doing this. You also have to take into account the raid benifit of having a ms warrior too. 4% damage is alot when you have 3 rogues 3 hunters and 2-3 warriors, your looking at 30%+ bonus dmg.
