pyxelizethis guy is nice as fuck
maybe outside of tf2, but within the game this is not true. every time i watch uni's stream he's constantly berating his team and generally being toxic. mind u, almost all of what he says is only directed to his stream chat and he doesn't dare tell any of his grievances to his team. it's abundantly apparent that when ur playing with uni u can expect him to give upwards of 60% of his attention to actually playing the game and the rest will be spent complaining about u to his chat.
that being said, mechanically he's basically the bar for low advanced thanks to 5 ping. outside of tf2 he seems like a swell guy but he is one of the last people that i would ever play on a team with just because he approaches the game in such an nonconstructive way. if he fixed this i'm sure he'd been fine, but for the time being i wouldn't recommend playing with him.
