Please do not detach Soraka's heal and self-heal
As it currently is on PBE, Soraka will be A LOT weaker than she was up until level 13 where she has maxed Q and W.
If she maxes Q she doesn't heal her allies and if she maxes W she doesn't heal herself and in turn does not heal her allies either.
This is a HUGE nerf, the only way she could keep up in the early and mid game is if she alternates between leveling Q and W and even then she'd still be largely behind.
I know they said tuning is still off, but I fear this particular change is going to make it.
