I had the unfortunate and absurdly expensive task of healing a tower of dispair the other evening. we had 1 person on Horoth, many people on Suulomades and I was healing both groups for lack of another cleric willing to drink mem pots.
yea me.
I wasted so much mana trying to heal people who were cursed. now, I realize, awesome solution #1 would be for people to get their own curses. let's just short curcuit that discussion and accept that the vast majority of people playing this game can't handle that task. if I had some sort of visual indicator on their health bar that they were in fact cursed, I could solve that problem too, or yell at them, or yell at someone else to fix them. anything would be better than wasting a prescious heal timer on someone who won't benefit from that.
so, suggestion: put some little icon or something on health bars indicating that they can't be healed.
