I totally second that even though I master him during the mystery portal this weekend he is by far 1 of the best chomper to use hot rod chomper is also pretty good but other than that the rest of them seem kinda meh. The teleportation allows you to sneak or go right by an opposing and chomp them for behind instead of the burrow which is predictable and easy to avoid if you see it coming. Aside from that I know Gw1 players work hard to get to 313 and probably have the right to disagree with my statement because believe my some of those quests were pretty hard but for those who never got a chance to play the 1 which have another equal difficult way of getting the Unicornchomper
