Right now if you make a healer you take an aura, slap compassion on it, and there you have the vanilla standard cookie cutter healer setup that everyone uses. Yawn your way to victory! Anytime there is a "vanilla standard cookie cutter setup that everyone uses" that's a problem that needs to be fixed.
Step 1: No more healer forms that scale with Presence. Compassion now scales with Ego.
Step 2: Add more offense forms that scale with Presence and more offensy support passives.
Step 3: Make auras have the same effect on other players in both Support and Hybrid.
What have you done!? I'm scared, change is scary! ಠ_ಠ
Well now if you want a healing form and an aura, an undeniably powerful combination, you have to put points into multiple stats. The reign of the aura-blasting super-healer is over. Now we have two other ways to go: the aura-blasting dpser, and the healer-that-actually-has-some-offensive-capability. There is quite a lot of highly relevant group content in this game, so someone who does decent dps and provides a strong aura will be an asset, and since they can now run in Hybrid they get to enjoy the better effects on themselves. Healers trade in their auras for the ability to contribute dps, being better at soloing, and in general having the opportunity to build something more interesting than a heal-spam-bot. Because of how strong healing forms are, a healer-with-an-aura will still be a viable build filling the "good at both, master of neither" niche, and as a result we now have three where before we had one.
