Radical thought...remove the off-tank?

[HoodRat]

Every raid group I asked in SB has said WAR is the preffered MT now due to Inner beast effectively giving it more mitigation uptime than PLD.

Inner Beast requires you to be in tank stance, which if the group knows what they're doing, you won't be in tank stance. Pld is the preferred off tank though.

Only off tank builds are the ones with the most dps.

Again, if your group knows what they're doing, neither tank will be in tank stance (except for certain spots in unending coil). Whoever does more damage comes down to which tank it is, what instance you're in, and the skill of each tank.
