So you are saying you used very slow or slow in M12 or M13? Also, I understand everyone moves slower but the issue with zig-zag running is the instantaneous change of direction, side to side, backwards and forwards.
So when I tested this last night in an online unranked game, very slow seemed to restrict those instantaneous movements, ie zig-zag running. Are you saying that when you slowed the game speed down, instantaneous change of direction was still possible?
