How to make Teemo competitive IMO
Firstly, make it so Teemo can store up to 10 mushrooms on Noxious Trap instead of three, and also make the charge receive time 30 seconds at all ranks instead of 35/31/27.
Additionaly, Teemo cannot store mushrooms on Noxious Trap while he is dead, or place them whilst in combat.
Huh? Huh?! Would that do it you think? Hoping for a Red comment!
