Warriors are the most broken class in PvP at the moment, and that's because of armor penetration and PvE-gear (especially with retarded weapons like Shadowmourne). I understand it's frustrating that warriors are so gear dependant that you feel useless with full honor gear and whatnot, but think about it if they balanced warriors to be good with that gear. They would wreck even more balls with top-end PvE gear, let alone with shadowmourne. So, they can't balance warriors properly atm.
PvE is also a reason why so many classes deal so absurd damage. If they nerf their damage, they at the same time nerf their damage in PvE, wich they don't want to. So, any drastic nerfs to damage dealers are pretty no-go, as you have seen during this expansion.
MS is also broken effect. 50% is way too much to balance properly, so it's no wonder they are going to change it in cataclysm. They are also getting rid of arp and making warriors scale... well, more wise would be a good wording I guess. So there is nothing to cry about, really. They are only making this game, and especially warriors, better in the future.
