Hmm. My BLM is only 56 right now, but it sounds like much if what you want changed strips away a lot of what makes BLM a BLM.

As a lv 80 NIN, I can also say that I can't even begin to express how jealous I am of the BLM ability Between the Lines. This ability has a Flying Raijin double function in that it also marks a spot on the arena for you to instantly teleport to. I am quite certain a knowledgeable BLM can use this in their favor to cheese some mechanics or to realign their optimization if their position is compromised.
