Collective Unconscious could probably be improved if its regen didn’t persist, or didn’t persist as long.

Say the regen only lasted for 9s, or three ticks. This could allow them to buff its potency up to say 150, and it would encourage its use as a channelled ability rather than just popping it once for the regen, because you’d fit more ticks in and those ticks would be more impactful.

Even better, would be if the regen diminished over time. Let’s say the first tick was 200, the second is 150, and the third 100.
This would mean if you channelled, everyone within the bubble would have a 200 potency regen. As soon as you move, or they leave the bubble, the regen starts to drop off.

Next to that, you could match that party regen with a personal refresh. 200 MP regained per tick, dropping off to 150 and 100 after ending. So popping it for a second is 4.5% MP gain, and channelling it can give you up to 10% MP back.
