But player C beats player A , 7 times and have issues with player B.
There is a difference in 1v1 and 2v2, because your good at 1v1 doesn't mean your good at 2v2. Yes you have skills, but i have seen plenty of good 1v1s who cant perform in 2v2, same goes for 2v2, you might be a good 2v2 but be a lesser skilled player of 1v1.
I never said anything about rock, paper, scissors.
Besides there the "best player" would be able to play any official WW any spot with any Fraction (gdi&nod) and have high win%. I dont see any one around who fits this profile.
You can name 15 top players, but ranking of their game play is constantly shifting since players get better, people take breaks, some come on/off.
