Would you be against or for rewarding good performance in parties?

The effect this (overhealing being a penalty) would have on healers would be tremendous. In a bad way. The last thing this game needs is to encourage people not to heal, or to avoid AOE heals because only two people need HP. No, no, no.

And indexing this off of healer DPS is problematic, too. If your party just likes to stand in stuff, you shouldn't be punished for it. How much I DPS is almost entirely dependent on the rest of the party, and whether the tank is doing massive pulls or not.

I don't know if there is an objective measure that's entirely under the healer's control. If they were to do this, they'd probably have to do something really simple like the number of times party members die (though even that can be beyond the healer's control).

Overhealing should be a penalty because you are wasting mp. Thus not playing right. And I'm not speaking any overheal. I'm talking about 10%+ overheal, which you see A LOT in dungeons.
