Most of the time he dies it feels like he has no chance. Spammed through the smoke, Gets killed from an angle that his teammate should have held, gets caught against lurkers and many other bullshit. You can watch the GenG game and you will know why I am saying this. People look at his stats and thinks wait why is he dying so many times? But if you watch the actual game, he barely loses a duel.
If I was his personal coach, I would just tell him to not trust his teammates with everything, just trust the intuition that someone has caught a timing and bait your teammates a bit more and play for trades. It sounds selfish but it will actually help SEN more. I can explain why.
