How to fix flash
Flash is the "must have" summoner spell because it gives so much for a summoner spell
Chase Escape Wall jump Skill shot dodge
It's the positioning "fucked up but its K" button
To fix this one thing needs to be done with flash
After flashing you are slowed by 50% for .75 seconds (the idea is it make it so flash is a burst of mobility but you trade burst for a net even due to the slow making it so flashing moves you fast but then if you just ran it you would be the same distance after that slow ends if going in the same direction)
This makes it still good for wall jumps, dodging skill shots, and a "last step for escape and chase, but doesn't give the "best summoner" feel to it
With this change flash CD might also be able to be lowered
