Ahri just feels very unrewarding to play atm
You can hit most of your skillshots and you'll get outdamaged by like every mid laner in the game, and if you miss charm/q you're basically a minion, a syndra can miss every spell but as long as she hits ult and 1 q she'll outdamage your whole kit with you HITTING EVERYTHING.
it gets even worse if you compare her to the actual top mid laners like azir or lucian/corki atm, all those champs can just use 1 spell and auto attack and outdamage her whole kit.
She doesnt have enough utility to be useful without doing damage (charm the only thing shes good for and even then, with one qss she has 0 cc left), her ratios need to go up.
