Koala is basically a cNed 2.0. OP heavy duelist who is great at jett but not so great at other movement agents. Also, Ange1 needs a duelist who will run it down and get 30 kills for him just how FNS and Boaster like their duelists. He has no use for a tactically sound player like koala. Even though I think koala is a great player, I don't think this move makes any sense from any of their pov.
