Tbh I don't see a glaring issue here. He is like a Yorick top. You pick him to harass your opponent and put them behind your team. You aren't going to contribute that much late game, there are definite counterplay options and he falls off late game. It seems like he thrives in an environment where no one wards. All lanes should be warding river in some fashion revealing your jungle entrances.
Personally I appreciate the control jungle coming back as a viable alternative to a gankfest.
