I used to assume that in 3v3 it's best to have your strongest player in pocket position. But clearly it is more complicated than this because a weak flank can outweigh a strong pocket and so on. Also play style is a big factor, as we see with aM – Liereyy's skill with crossbows makes him an ideal flank player and Hearttt's skill with knights makes him an ideal pocket.
So what are the attributes that make for a good flank/pocket player?
