My guild and I are running HMTFB regularly and getting stuck at 13% with the writhing horror.
We are running the strat from dulfy.net and doing everything to a T.
We all have full BH augmented and even a few 27's here and there.
Did anyone else while learning the fight seem to hit the enrage here too?
What did you all do to pick it up just that little bit ?
As others have posted already, taking WH below 15% after the 3rd male is dead is crucial. Other things you can try is stacking in the melee group for AoE heals and full coverage on your group from gunslinger/sniper shields can make a difference too. Make sure your tanks are AoE taunting whenever there are several adds running free in the raid.
