my thoughts on ahri
Coming from an ahri main who has played her when she was both strong and bad.
The reason she has seen few changes to her actual stats, is for a large majority of the time, she is like Lee sin when it comes to the meta. She is dependant on who is and isn't meta. She is also dependant on which items are strong and not strong.
Right now both conditions fit ahri. Champions she hates to face are out of meta, and items she loves to use are very in Meta. It's a double win for Ahri at the moment. Champions she loves to work together with are also very meta. So slash that it's a tripple win. This is a large cause for the sudden inflation of ahris win rate and play rate.
So where do we go from here?
Personally I believe the best nerf has nothing to do with her passive or her movement speed on q. Which many people complain about. No clue why, if Riot removed them this would legitmately change nothing about her.
So what I believe should be done is a very simple and clevor nerf.
Ahris Q has 2 forms of damage since it's a boomerang ability. Heavily nerf the damage on the first Q but Buff the damage on the second Q (the returning) This way bad ahri players are heavily punished for when they miss the returning Q and good ahri players are rewarded.
if this isn't enough we can also nerf the damage on charm and increase the mana cost on charm.
These two nerfs I believe would be a great way to nerf ahri without gutting her.
