Whoah I should have posted in here sooner.
Yellow was the player on ESD we could count on to not feed and not rush things and be the last person to lose his level-headedness.
He has really low deaths, but generally still puts up solid numbers. He's a pretty rock solid combo demo, who doesn't even need a lot of heals, so while you won't really see him going for insane plays too often, you can count on him to do his job, quietly and as efficiently as he can manage.
Long story short you never have to worry about what he's doing, and he only needs a confident main caller to urge him on and frag, because he does have some confidence issues.
Please at the very least put him on a nice, high open team, easily the friendliest gamer on ESD.
