To debate #6, since its been proposed to me numerous times. Invisibility is, not particularly helpful in the Gorgon Maze. It can be, but timing is required, and you can just as easily time your movements without invisibility. You're probably better even just using the speed sprint to get through narrower windows. Gunslinger has a super which is more viable against bosses, true. It also does less damage and is more squishy then the BD with general use guns. There isn't a huge amount of long range sniping to be done, in the VOG to cater to the Gunslinger. Whereas the BD has the super that can wipe out large numbers of close(Showstopper) or midrange (Arc Wave) mobs while healing itself continously (Hungering Blade). Toss on super-speed to move with relics, cover fallen allies points, or hit Oracles. The Golden Gun is kind of easily covered by using appropriate heavy weapons (and prepping with a decent number of synth packs) to drop the Praetorians and bosses. I haven't been raiding with my warlock or titan to really dissect those, but the Super ability is probably not a big deal compared to a proper loadout of weapons. From an outside perspective, Defender seems like a terrible Super to use, as it prevents you whittling down the hordes as much as it keeps you alive (and Praetorians/Minos/Fanatics/Supplicants will come inside and break you)
