Ok, go level a hunter and use them in PvP then report back. Both hunter supers make unmistakable sounds when popped that alert anyone on that half of the map to seek cover or counter them with your own super which happens to provide no such warning sounds. Golden Gun gets no defense buff. I can't tell you the number of times I've popped it only to be shot dead during the animation. And guess what, unlike the Titans fist of Havoc or the Warlocks Nova Bomb, once the animation starts the super is spent. If you get killed during the animation for either Warlock or Titan your super remains when you respawn. Also Golden Gun has three shots normally and four if you have the exotic helmet, I have killed an entire fire team of 6 with fist of havoc and 5 with Nova Bomb. The most I've killed with Golden Gun is 3 and I've killed 4 with BladeDancer. Oh, grenades... You mentioned the only Hunter one hit grenade. The Titan and warlock both have much more effective grenade options. Lightning, magnetic and Pulse grenades are all incredibly effective as are fusion and axion bolt grenades. So again, go make your Hunter and report back on just how OP you think they are.
