I'd rather Healing Magic skill affect the Stoneskin effect from Solace or a MP refund similar to the effect of Orison Pantaloons +1/2, if it's a White Mage specific thing. People only have so much HP and I rarely let anyone lose the major of his or hers, so the idea of Cure V healing 1200 HP instead of 1000 HP doesn't do much for me.

If it's a universal change, anything is fine as long as it has no negative effects. The Cure line was designed to work pretty well from a sub-job, and I think that's just neat-o.
