Pushing aggro on HM Writhing Horror really isn't an issue. If the tanks are good (as in know the fight like the back of their hands) then they can go with the flow.
It's HM Kephess where this has made me go "Nooooooooo!"
Ever tried healing when the Walker goes down in 2 tries on HM rather than 3? We did this cause we thought it would save time. Well it didn't cause we died
Why does BW want our dps to sit on their thumbs during the Walker Phases? I don't understand the purpose of having our dps just sit back and pick their noses.
