I think the biggest problem here is the skill distribution. Golden Gun, at 20, has skills that shorten it's cooldown, make it more accurate, increase the range, and make it explode and/or penetrate when it gets hits. Unfortunately, only Keyhole is available in the beta, which is the first major upgrade to GG (accuracy doesn't seem to matter unless paired with range). Titans and warlocks on the other hand have way more upgrades to their supers. Warlocks get the void zone on nova bomb as well as lingering void zones, where Titans get aftermath (damage zone where FoH goes off), a long jump for FoH while sprinting AND a talent that specifically makes them harder to kill when using FoH. As a result, locks and titans have much stronger supers at this level because they have several skills that enhance their supers and can't skill away from because they don't have any other options. GG, therefore, seems to fall behind. At 20, this won't be the case, however. A GG with explosive kills, extra range, and penetration has far more killing power than a single titan super from a much longer distance. I can't even fathom how insane it will be if you stack Intellect and take the cooldown talent instead either, making GG the fastest recharging, longest lasting primary subclass super in the entire game. Lastly, I have experienced getting oneshot by shotguns before (wasting a GG) and it sucks. Unfortunately it's just a hard way to learn how not to use the skill. It sucks, but when you come back with a shorter cooldown and longer range, you'll be making up for those lost opportunities and then some.
