Super Good Advice used to be one of the worst Exotics in the game, right next to Bad Juju. The main reasons it was very subpar were because it had absolutely no Stability to speak of (Hunter's Gunslinger's Trance ability only goes so far) and its core Exotic mechanic is that it requires you to miss your target in order for it to come into effect.
