The usual spouted nonsense from people who don't know how to BLM.

Learn the fights. Learn which moves you can ignore with ward/wall. Learn which you can't. Learn phase changes so you know when to use/refresh enoch. Learn when you are likely to absolutely have to move, and plan your procs, swifts and teleports (and at absolute worst, Scathe XD) around it

Apoc probably isn't used very often. This isn't because it sucks, but a lot of BLMs for some reason decide to ignore this awesome ability in their toolkit

BLMs sure are the least mobile of the dps, but to say they can't move at all is pretty silly. The whole challenge of BLM is learning how to keep your movement to a minimum, by planning ahead
