I do think there's a couple minor hitbox issues with it, but they're just that: minor.
It's a little awkward when you're on blue side, because it looks like a part of it hit them when it didn't, and it's a little awkward on red side when you think it missed, but suddenly they get pulled.
I don't think it's completely unreliable, I just think there are a couple weird areas right at max range (particularly at the corners of that range) where the hitbox seems finicky, and the model doesn't quite line up completely with the hitbox. I've only played a couple games with him though, so it's honestly hard for me to say for sure whether that's a hitbox thing, or if I need to consult my optometrist again.
