even back when he played it in shanghai he looked extremely uncomfortable on all the characters utility wise, his entry pathing was garbage and the only reason his stats looked so good is because of the team's system and his mechanics which bailed him out
that performance wasn't sustainable and you could see in the maps they lost he (in particular) looked completely clueless
you could argue with more time he'd be good on duelist but at that point you might as well be calling for every mechanically good player to go duelist. leo? go duelist. mako? go duelist. karon? go duelist
also anyone who thinks TH was better in shanghai than in champs needs a visit to the nearest neurosurgeon
