I'm not even speaking about the SEN series at champs... Boaster was 2nd to last in ACS, and underperformed the whole year. This is also to say he's actually pretty decent mechanically and has improved.
He's the IGL but you guys can't bash him for a whole year and then act like he'd be a top fragging igl on a different team, it's unrealistic. Top fragging IGLs like Valyn, JohnQT, Munchkin, Boo and Nobody are all great aimers while being IGL, yes Boaster is a great IGL even with his inconsistencies as an aimer.
Playing with good players doesn't make you a worse player, it's not like he's not seeing enemies. Horrible Gimmick.
