Its true man. Us titans or the "melee" class actually have the weakest melee for some reason. No range, you might get lucky with a random lunge but for me its better to hope they're in hugging distance. Strikers have no special effect melee like the other classes and you have to give up living through a super to have the one hit melee (which is balanced {at least to me} since you have to be sprinting and its very linear meaning any action outside jumping will cancel the effect). Its also not my style to get into shotgun range. Defenders just have to kill someone for their effects to activate so nothing to say there.
