@riot you are nerfing the wrong thing (ahri nerfs)

ahri with her standard build have a 50%~51.8% win rate,the real problem here it's the glacial augment build that have a WR between 54.6% and 58.8% which is raising her global win rate so much

why you have to cripple her standard build because another build (which is broken on many other champions atm) is too strong?

this nerf won't even affect her glacial build too much since the whole point of this build is turning her in a support,CC her enemies and then land a free charm (which after the last buff last more) and let your team kill them she doesn't really need her R for engaging someone,she doesn't need it for making "plays",she just clear with her Q and catch her enemies with + + E

basically after the next patch the only viable build will be the glacial augment build,which will still be broken

the worst is that this build is exactly the opposite of what we (ahri mains) asked for when we wanted some work on her kit,for the joy of anyone who's going to face her this is probably the most passive and uninteractive build of this game,almost infinite sustain,many CC and she basically afk clear her lane untill she can catch someone with her slows

so much fun for both sides

the simplest change would be revert her E buff and try to change something else like her W or nerfing the glacial augment build (which as i said it's a problem on everyone,ahri is just the best user)

or since her last mini-rework was a total fail (you wanted to give her less safeness and more rewards but it ended up in a more passive,inconsistent and binary playstyle) you could put some effort in it and give her a true mini-rework ( sized) changing her abilities that give her unneded safeness/power like her passive ms (useful only as escape) and her Q heal (which is terribly inconsistent in a fight but too good when you afk shove the waves),her W targeted damage and since we are at it remove her E amp,we saw it from old nidalee and zoe,too much power in one ability is not easy to balance nor fun to play against

edit : i also want to remind how much ahri rely on her ult,so even 20 sec are going to hurt her so much especially against champions like who have 100 sec on their ult (30 sec of difference is really huge)
