Has the balance team realized how much of a mistake it was to simply add a movement speed to her Q?
But nooo because "She will be bad after the DFG removal"
so far despite the nerfs, she still remains strong for 3 years now
They added that a LOOOOOONG time ago...
She has little damage, that is her weakness.
High mobility for lower damage, Just dodge her charm and win the 1v1 (Unless she is fed!)
Learn and pick 
into her. Literally one of my favorite 'lanees' as a kat main. Almost always get 1st blood on her by level 3. Poke, bait out charm, and kill with QE auto W E auto ignite (chase if needed). Kats ult is just overkill once you get ludens and hextech
Or 
if you want to be a bit more risky. Assuming he isnt banned the lane is a VERY UNFORGIVING skill matchup on both ends.
ahri is op so op op 10000000000000000 dmg 1 sec
I'd just like to see CD changes on her ult, either its base cooldown or the cooldown window for each individual dash to be made bigger. She's strong because she's too safe. She's average when it comes to damage, it's her design, but the fact she can play so passively with her passive and ultimate makes her less likely to lose lane. Either cut back on her safety later on, or remove the Q MS to make her a little less slippery in lane.
She's strong because she never loses, not because she always wins, which sounds awful.
