Honestly people seem to be overlooking how easy it is to enter and leave WM. Its nothing like a BLM. A BLM cant instantly drop their cast times and run and gun. The only restriction is that when you activate WM you need to be ready to be in it for 15 seconds. There are heaps of times in fights where your just standing still shoting for ages where WM shines. Its also a big bonus in AoE situations.

Maybe its cause I'm coming from playing a lot of WHM but droping in and out of a stance really doesn't seem that burdensome.

BRD doesn't play like BLM and people who think it does, don't play BLMs.
