Warriors are, as expected, super gear dependent.

You really need to get basically MC/Ony geared to some extent, before the issues with rage start to go away. However, once you get to the point where your warriors are generating enough rage to sustain themselves without incoming damage being a huge part of their DPS potential, well, you're going to mow content in a way I'd guess no other group composition can.

The issue is, getting 3 or 4 warriors adequately geared in MC/Ony gear. That's a lot of pug raiding I'd guess, unless you have a raid group that is willing to feed all of your characters.
