Without supers its about player skill, with supers it goes as follows: fist of havoc > golden gun > nova bomb > arc blade sunsinger and defender are equal on their own level of play imo. So with this a titan with full armor and the harder to kill perk will kill any other super while living, Gg kills nova bomb and arc blade, nova bomb kills arc blade. As it stands the arc blade is second easiest to kill next to golden gun bit has the disadvantage of being melee. So regarding supers, yes if u wanna look at it that way the titan n warlock supers can b considered "op" for completely stopping yours but outside supers vs bad players arc blade reigns supreme. Not regarding supers if ur losing, u r just not as good as your opponents.
