eh... make WM more like a normal song instead of a stance. It could be reduced MP drain so it lasts longer/doesn't totally kill your other song (like 1mp/tick or something), or just a flat cooldown timer. Setting it to flat out drop when you move would be too problematic and probably raise just as much a crap-storm as it's initial implementation.

BLM... might be a bit too OP. Not sure exactly, would have to see how it played out I guess. You can already slip 3 Fire4's in one cycle of Astral Fire, so the extra 2 seconds wouldn't necessarily break the rotation I guess, but it might unbalance it a bit as our Spell Speed and crit rates get higher (more firestarter process and quick casts of fire might swing things the other way over time).
