If you want to make Soraka more focused on hitting her Q...
...then why the hell is new Q self heal at rank 5 worse than current W self heal at rank 1? She's going to be absolute shit if these changes come out as they are now.
Unless you want Warmog Soraka to remain the only even remotely viable way to play her, that is. Because she has far more interaction and counterplay than AP version you are completely destroying with the incoming changes.
