BLM doesn't need a nerf. BLMs are paper bags that get killed by almost anything and they deserve to have a high damage output (which really isn't as high as people think it is) DoWs deal damage continuously without any meangful costs. MP does limit mages, especially if they're taking hits.

We just had a balance update that buffed almost every DoW except WAR, and nerfed an ability that contributed to a BLM's ability to do damage without risk. It's fine.
