Typed the following into search and come up with nothing: Divine intervention, yogg, extra brain dps.
So we were on Yogg tonight, still havent killed him. Yes i know we suck. And a wipe was called, so 1 of our rets DI'd a boomkin i the brain room. Induce madness finished casting, Boomkin didnt get MC'd. Removed DI, continued dpsing brain.
Basically what i'm trying to say is, DI a dps in the brain room at 5 seconds left on induce madness, wait til induce madness finishes casting, and remove the DI, and you're free to dps until the next induce madness cast.
You can also soulstone the paladin that di's so he can insta res once he's thrown out.
I'd love to screenie it but we're still DI'ing the boomkin :P
Will get some proof later if pos, otherwise try it yourselves.
