Is it actually broken? It seems like that corner "infinite" can only do up to average B&B damage before putting the opponent in a state where he can burst. The last arc hitting for 100% life is nasty but usually when someone lands a last arc it means the round anyway. Overall, Archetype seems to move fast and do a fair amount of damage but, though I haven't unlocked it to test for myself, I haven't seen anything so far that necessarily makes it indisputably stronger than every other character by a significant margin.
