I play bladedancer in crucible and if you look at my stats super doesnt account for much of my kills. Its a mode switch and leaves you quite vunerable compared to using only guns and staying at a safe distance. Like other supers it really shines when a group is clumped together. In my exp if your further than 30 ft away when someone spots you in super mode you can be killed quite easily. Another complaint is BD super can run all over and kill the whole team, ive never killed more than 4 ppl in one super they just dont clump together like that and most of the time i get 1-2 kills. Edit1: I went and looked at my kills 164 super kills out of 1614 at time of writing this comes out to 9.8% so while its a pretty good super it isnt the end all be all.
