So not "easy" so much as "mechanics that don't wipe the raid if just one player screws up", I can totally understand. Nothing quite as frustrating as wiping on old content because it's just that unforgiving to a death or two. Still can't manage to beat mythic KJ with my guild due to having several such mechanics...all of which activate at the same time, most of which require you to do different things, and there's an entire phase where you have to do all of them at once while totally blinded.
What sick bastard makes boss fights like that?
