Just throwing my idea out there, it's very similar to the others.
Shatterpoint:
Add: 100% expose chance, 50% chance to apply Deathmark instead. In addition, Mace Exposes all buffed enemies at that beginning of each encounter for 2 turns!
Final text: At the start of each of his turns, Mace Exposes a random enemy until the end of his turn, with 50% chance to apply Deathmark instead. This effect can't be resisted. In addition, Mace gains 25% Turn Meter when he attacks an Exposed enemy, and at the start of each encounter Mace Exposes all buffed enemies.
As a side note, I would love to see his Smite ability changed to be an AoE dispel (maybe with slightly reduced damage). It's rather lack luster as is, especially when compared to say Qui Gon Jinn's dispel. Maybe also change his basic to deal special damage.
