I don't play nor like Ahri, but...

.... yeah, the charm nerf is kinda stupid, and the arguments brought up to support it by riot are a bit... underwhelming. When it floats your boat, stuff "separates the good from the great"... when it doesn't, it's because _"consistency over other CC". _ Charm stopping dashes is:

• thematically fitting and unique
• helps against mobility creep (honestly, more skills should stop dashes, not less)
• power budget relevant only situationally and/or on skilled players, so it's unlikely to be impactful as a nerf
• removing it strips away more fun than it hepls balance

I won't express myself on Ahri's balance state, nor do i care.

If a nerf is needed, which can be absolutely legit, making is Q movement speed come out only if the spell hits champions sounds more reasonable and overall a better choice design wise:

• rewards skill and increases counterplay: if her charm is off and i manage to dodge her Q, i deserve to close up and maul her face: this is fair but right now it does not happen. Here i'd put a fix.
• lowers significantly ahri's safety and punishes bad plays, so it is an impactful nerf
• does not hurt best-case scenarios
• prevents the unintended usage of her Q as a mere mobility tool; i often see ahri players throwing it backward only to roam faster, or in order to catch up in a prolonged chase

This is coming by a mostly immobile tank/bruisers player, who if closed in a room with Hitler, an Ahri player and Stalin with a gun with 2 bullets, would shot the Ahri player twice.
