I agree with the ultimate sentiment that sym has always been, even at his best, extremely inconsistent. If anything, as someone who has watched him for multiple years, I’d actually say he’s been playing better this year after the disastrous stint on EG.
I have a hunch that his problem, like a lot of t2 talent, is that he requires a distinct level of coaching and accountability from teammates to improve on specifically his consistency. He’s been around a lot of the same players for a while now, and no dig to them individually as players or performers, but sometimes that kind of continuity can stunt players if they’re not overly self-aware and constantly receiving AND seeking feedback in good faith.
TLDR: sym’s weaknesses can be broken down more as inconsistence than straight up awful game knowledge/overheating/mechanical skill imo, and breaking that cycle to work towards becoming a reliable duelist will require intentional change from him and those around him.
