I can spam Deadfall. The only real super rhat sucks is Silence and Squall. I'm sure there are more that don't do what they're supposed to, but that's the only one I can think of right now. What is it supposed to do, you ask? Generate orbs when it kills. When combined with Spirit of Galanor on the exotic class item it's supposed to generate super energy. It doesn't. That's the only problem super I can say.
