If the real intent is to balance and not placate, Ultimate points gained from healing should be based on healing and not casting. We can still cast healing springs (or any heal) on a group of players waiting for a fight to start and gain ultimate points even though those players are at full health.
A DK can just cast resto staff heals on players, drop a standard and still put out dps on par with the single target speced players in the battle. If we're going to be fair Ultimate points gained from healing should come from actual healing and not just hitting someone with the spell.
