Nah ZeRo4's movement wasn't bad. You should have seen him during Challenges 1, now that was bad! He just didn't know the map which btw was (is?) gellehsak's best.
Gelleh is nuts, attacking from like 4 directions at once on cpm15 with those teleporters and sick moves, coming in from completely unexpected directions, impossible to predict :D
Good watch.
