On later lvl's snake pretty much wins the field by itself since the utility of it, like wasting enemy's misteries and getting your barrier up, is op on it self, and not even counting the dmg the serpent deals in later levels. Our serpent is lvl 95 and with that swipe attack it can kill ninjas from a 70k player, and with its 45k health if i am not mistaken is tanky as well. It all depends on your competition in GNW so its rather subjective, but overall snake, once leveled up, is insane and basically game winning, at least on my GNW.
