On one attempt that we positioned her "correctly" , we got the final eredar twins to 51% with a whole melee group dying before red is even halfway dead. We had over twenty attempts before that where we never managed to get past 40% due to shadowfuries on the raid.

Anyways...has any tanks there found a way to ensure that she does not shuffle around? We tried standing on her face, max distance ( accounting for tauren hit box), and even everywhere in between. We tried variations of tanks stacking on top of each other, along with variations of Brutallus-style positioning ( one tank on the boss, while the other is around 90 degrees to the left side of the boss), but it always ended in one thing : the boss moving around, even if confounding blow or aggro transitions are not factored in. This makes for one hell of a constant, fixed positioning to ensure that shadowfuries do not reach the raid.
