As an Ahri main I'm happy for them to take the Q movement speed boost away
Just return her W/R range, her E damage amp and Q mana costs.
Like pre patch 5.2 she had a reasonable winrate 49-53% and a decent pickrate 10%~
Yes she had a fuckton of damage but her mobility was gated to her ultimate so she was very unforgiving if you missed your Charms or wasted ultimate.
Like isn't that the definition balanced assassin? Moments where they are weak (ultimate cooldown/Charm cooldown) and moments where they are strong? If she misses her shit even an AD can duel her easily.
DFG isn't here now so even giving her damage back won't suddenly turn her into the next LB. The mobility seems to be what irks people.
