I'm honestly finding it hard to believe that everyone seems to be incredibly disappointed over Ahri's changes. A huge part of this patch was removing the necessity of one cast to completely annihilate a person with the following spells. While I've yet to use her post 5.2, I honestly still think she's strong. Charm still gives an incredible advantage to Ahri for a brief moment, where she is still able to land 2-3 other spells on her target while they're helpless. Her Q movement speed makes her an excellent kiter as well. In fact, now that people will focus more on her mobility, I see her as more of a menace in team fights, providing a necessary form of crowd control for at least one enemy, which your whole team can collapse on for basically a guaranteed kill. Need to escape a bad team fight? Throw out a charm to slow your closest chaser and then pop a Q to increase your get away speed, and slow them if you've also built Rylai's. And let's not forget they patched up her ultimate collision, so it's a bit easier to hop walls to escape danger now, and let's not forget she has those 3 dashes available on a relatively fast cooldown. I guarantee she'll still be strong if people can adapt to her altered playstyle.
