even if Perfecto was much cheaper, I would still choose sdy if I was NaVi CEO
He has more lan experience and has played against decent teams. He is a perfectly versatile balanced player who can do everything from supportive kind-of roles to entry-fragging or even IGLing. And he is pretty calm and chill in-game.
With somedieyoung NaVi would have had the potential to become a top3 team and they would eventually pay off the buy-out sum after a few tournaments attending.
Please fire the man who's responsible for roster moves.
