Illusions. Making illusions that can do minute healing/dps passively, attract enemy attention for solo'ing, etc...
Over Healing. Tank at 50,000/50,000 HP? Keep going. A few seconds later, they're at 56,000/50,000 HP. Get them up to 100,000/50,000 and give them a DPS buff. Make this available to all healers and it could make for an interesting dynamic in how tank busters are handled.
