I'm more or less of the mind that they're fine as is, at least as far as animations are concerned. I think the healer LBs need to be tweaked mechanically, as they feel entirely useless 90% of the time, but that's another topic entirely.

I'd rather they devote resources towards making more unique class and job specific abilities than personalizing the LB animations. Also, changing Monk's LB3 would be silly. It's technically already a monk ability.
