My comment was intended to be a criticism on his design, not a complaint. I don't think that Elo and win rate directly correlate with a janky design. Like Akali's design is horrendous, regardless of how high her win rate happens to be.
And honestly, I'm speaking to it from experience after putting 100 games into Pyke, which incidentally, I ended up having a 58% win rate in gold, which seems really damn high for someone like me who's historically played Enchanters.
I personally feel like he can't be properly punished for botching an engage, getting caught out, or getting hit with poke. But this is completely off the topic of Aftershock on him.
