I use Radiant Skin when I'm required to put myself at risk. It makes you practically unkillable. A relic holder should never be dying. I'd rather someone who knows enough to not die with it - there's absolutely no time in the game where a relic holder should be in real trouble* *the exception being stuck with bad teammates when teleported by Atheon. If the oracle-killers aren't helping the Relic-holder when needed, it's their fault, not the relic-holder's. Of course I've wiped in the raid - often. However, I can think of one (and only one) example where self-res stopped a wipe: playing hard VoG for the first time, made it through the confluxes with four people left and everyone died on the final wave of legions. The warlock was able to res and hide. But then, if he'd been using Song of Flame, we'd have all been a lot more powerful and would have had an easier time fighting off the legions.
