I've tested both skills in pvp and they do similar damage in WoE. Cart canon is about 8k-9k pvp & woe, knuckle arrow about 14k in pvp and still 1 shots low lvl 3rd class in woe that have ~12k hp. Knuckle arrow seemed to be reduced by demi human reductions in pvp. I don't know what tests you've done that conflict with mine. I could be wrong but I am going from the info I have. It doesn't invalidate my point these skills are bugged and don't check various game damage reductions.Kaddybb neither cart cannon nor knuckle arrow ignore woe reduction... they ignore demi human reduction entirely/partially though. So do plenty of other skills though D:
EDIT: the only skill im not sure if it ignores WoE reduction is exceed break. Since it's a melee hit? I've barely managed to get certain peoples damage to a livable level(when they use the weapon swap trick) and the damage seems identical in WoE. Not thoroughly tested though.
