You know, the bug that made starfall pull mobs you were not in combat with..
I can't yet perfectly gauge the radius of starfall while I'm moving and the other night I got blamed for wiping a run for popping starfall, tank said it pulled group across the (smallish) room. Not having seen it do that, I'm scared to ever use it again and it is a primary part of the boomy rotation. Blizz QA should have tested that before going live imo...
