Ekko's W (active) is fucking useless.
If it wasn't for the passive I wouldn't bother with this skill. 3 fucking seconds? Riot, you attempted this crap with Cho and Gragas. and you ended up fixing it MUCH later, can you just not be retarded and fix it now?
Better things to do with W.
Make stun last 1 second, activates only when Q is sent out. Moves along with Q.
The synergy is real!
