I wish Luna's ult was 12 seconds and she got it faster but the healing was severely nerfed.

Maybe somewhere between 50 hps - 100 hps?

I feel like it would be more fun, but less oppressive. You could kill people through it with coordination.

Also have it maybe have a severely weaker damage boost on at all times without having to switch off healing.

Nerfing the healing and/or damage boost until balanced pretty much.

It would be an interesting change. MORE DANCING!
