howto correctly nerf soraka top...
Please Riot, the nerf to soraka-top, which was supposed to have "no change to support" had a huge change to support.
If you really want to nerf soraka top.. then make her cast her W to heal herself, which she can't do in a solo-lane.
Make her Q build up charges, which upon casting W, will heal herself. Then she won't be able to sit in a solo-lane and spam Q to heal herself, but she also won't need to get gutted as a support.
