Blade dancer is a super i repeat, super, they are not supposed to be easy to kill. What good would a super be if it is a melee super that you always die with? Supers are supposed to be countered by other supers, a titan smash, golden gun, and nova bomb will shut down a group of blade dancers. Any prolonged supers( over time ability, gg, bd, ss) have to have some kind of shield or damage resistance so that they have some effect. A super is powerfull enough to level an entire team if used right, not get 1 or 2 kills and die after.
