BLM too. Erase has a use!

It also has a long cooldown, and I've never once seen a BLM cast Erase. Expecting your average Duty Finder BLM to know what Erase is, or have the forethought to actually cast it.... meh. I'd rather not. I mean, there's Mana Shift, and I think out of every 20+ BLMs, I'll see 1 that uses it on the healer.
