Really really solid mechanics but hes honestly kind of a dumbass. Sometimes when ur just hanging out with him in mumble he'll make stupid noises and will sometimes say distasteful things and is generally unlikable by people that aren't just like him (or at the very least enable his behavior). He'll say he's just trolling and is doing it as a joke but last time i checked jokes are supposed to be funny. Bowl also isn't really the type to read a room and will just keep rattling off if nobody is responding positively to his tactless "trolling." I find myself local muting him within seconds of him joining a mumble channel im in (and i know im not alone). If you're the type of team whose players hang out with each other often outside of scrims and matches i doubt you'll enjoy his company for very long.
All of this aside, he is a very fast learner and he will only get better, not to mention he has a very strong presence in comms, which makes him a valuable asset to teams lacking vocal callers. A strong pickup if you don't mind his eccentric personality.
edit: By the way, I fully believe bowl is capable of being an all-around great teammate, as I have had normal conversations with him before without it devolving into a meme cesspool. He just has to get his head out of his ass.
