You can shoot them with half a clip of an auto rifle while they are moving towards you and get their health in the red, then melee them and they die. Sure they can still kill you but you will kill them as well, which makes their super pretty pointless as they exchange deaths as they could have by simply shooting each other. Warlocks with sunsinger take a crap ton more damage before dying, and they are able to attack from a distance with guns and grenades, voidwalker and striker can fully use their super with suspended damage making it where regardless of how much you shoot them they will not die until their super is out, thus killing people they were going for without worry of dying prior to killing anything. Defender can sit in the bubble with a shotgun and kill anything pretty much aside from possibly a sunsinger as they get insane damage reduction and extra power with their melee. A bladedancer has to hit a defender twice in the buble to kill them, in which time they can be killed easily by a titan with a shotgun. If timed right, a shotgun can take out a blade dancer while it is lunging at the target too without even killing them. Yes, they have the shockwave they can use, but it takes time to go through the animation and can be avoided quite easily if seen. There is nothing that can be compared that I have seen to how weak the bladedancer actually is. People make it seem a lot more deadly jsut because it can move around fast and if used right it can take out a whole team, but that also is dependent on the team not seeing them and reacting in time. 2 people shooting together can easily kill a dancer when it is in striking distance.
