Things I think need fixing up or changed.

A lot of those things are holdovers from early MMOs, or even from FFXI in particular. Hopefully someday we'll see some of those change, particularly movement while casting.

It's largely a balance thing, think about it, if they let BLM's "run and gun" and damage had no effect on casting, then with their nigh infinite MP pool they'd be unstoppable murder machines. To compensate they'd need to either severely nerf the actual damage of spells, mp regen, or up cast times... or all three to keep BLM from being OP.

Same with healers, they'd have to find another way to balance then, that in the end would be worse than having to stop an cast.
