I main a hunter and I can say in my team 2 warlocks a titan and 3 hunters (including myself) it is usually me that holds the relic or guide the team through the whole VoG. Don't get me wrong, that my team does carry me from time to time when I am just having a bad day doing the raid. In my own opinion Self res on sunslinger is amazing, but if your warlock happens to be a bad warlock and dies pretty easily then self res becomes pointless if he happens to die during it or a couple seconds right after radiance is over. During Atheon, gunslinger has its ups and downs. Easy oracle and add kills. But what I have seen is horrible damage while using golden gun. But fret not during times vengeance trip mine grenades (if you can land it or have atheon step on it) does aroun 1-2k damage sticking him and another 6k+ damage on explosion (from what I've seen). Bladedancer I would have to say is not much of a help seeing how arc blade has to put you in close combat. Titans do have their ups and downs too with their shield, but once you start getting overrun by supplicants and they come into the shield then its pretty much game over if you don't manage to escape lol.
