Singed Buff Idea
As a Singed main, I can tell you how terribly frustrating it is to watch people chase me and gain HP while just sitting in my poison sometimes. This shouldn't happen, like ever, unless I have literally no AP.
My suggestion is to add a healing reduction to Singed's poison trail, maybe not Grievous Wounds strong, but something along those lines. If you are sitting in poison, you should just about NEVER be gaining HP, unless your kit is built around healing, like Aatrox, but even that should be greatly reduced.
Thoughts?
