RGM Idea: Champion Abilities Now Contain Endless Range
The video inspired this idea.
Basically every ability in the game is global.
To prevent things like lvl 1
pentas and
never leaving the fountain, abilities are unable to be used in the fountain and entering the fountain ends all lingering effects like singed poison trail. To prevent camping, you can leave fountain through the walls. Probably should throw in some untargetability while in fountain to be safe.
Since this would be blind draft you can get rid of the most annoying champions. Looking at you 
This is probably a terrible idea but I want it.
would one-shot everyone in the fountain at level 1 with an undodgeably fast Paddle Star because its damage and speed scale with its distance.
