Fixing Ekko's Q bug made his Win Rate drop like a rock - Any plans to help him out?

Now, I totally understand that unintended bugs are not a nice thing to play against, but after it's removal, I can personally feel Ekko being weaker in lane, because it becomes much harder for him to pressure the enemy champion, since they can easily move out of his Q.

HOWEVER, I didn't think this would be such an issue. Surely, you simply E onto them, then use the Q and ya know, do Assassin things. But apparently I was wrong, because this patch, Mid and Top Ekko, which were previously hovering around 50 and 51 % respectively, are now both sitting on a 47 % win rate.

Maybe something else happened, maybe I am missing something, but I feel like this bug kept Ekko afloat, and with its removal he fell hard.

I implore you Riot, please, find a way to make AP Assassin Ekko decently viable in Mid and Jungle. I'd like to feel comfortable picking my favorite champion, but right now it feels like a gamble.
