SMN: seconding the request to improve tri-disaster. Larger/better graphics egis. Make Miasma II tpbaoe.

SMN/BLM/ARC/THM: It would be nice if they could cross-class esuna/leeches/got their own dispel-type ability.

WHM: I'd give it all for group stoneskin, I swear it. Oh and a larger radius for Cure III. Also, a sound more like angels singing when Holy is cast instead of that annoying crashing splosion sound, as a bonus!
