We do phase 1 a lot differently. We have our pally MT tank the ghouls and shamblerss off to the side and have people who get the plague run over. He keeps it bouncing himself. He constantly taunts the ghouls over to himself when they spawn.
Once the transition phase comes in he tanks whatever is left off to the side and eventually the plague kills everything all on its own if done right. After that he and our druid tank swap roles and pally tanks LK while druid taunts the remaining 1-2 spirits in phase 2.
My new guild does this, it's obviously how they intended it.
