All characters have something of the color of their team. All Pirates have something red. All Knights have something blue. And ALMOST all Vikings have something green. "ALMOST", because Berserker is dont even have something green. That's probably because Berserker is one of the first classes in game. So I think that Berserker also need something green, like green paint on his torso and/or face. Then, all Vikings will have something green. We need that for full symmetry.
