I'm already less of a burden on my warrior. We sell titan all the time and I fill a DPS spot on my war and crank out as high as 300 dps on a good run or 200+ on an average run.

The proper way to fix this problem is to make every 8 man have two tank mechanics. Gaurda HM is already that way. Titan HM they could make it so mountain buster applies a debuff so that if you take a 2nd mountain buster it 1 shots your azz unless a tank taunts off you and eats the next MB while your debuff expires.
