Saving the group when everyone fails is support. I might have died last, valiantly trying to revive you from where you charged in and got yourself vaporized. If I have to save my super the entire nightfall just in case we all die, then I call that support... I'd much rather be killing groups of enemies with my Obsidian Mind and Bad JuJu setup than sitting on my hands just in case. If a fusion rifle is Plan C, then this is Plan D, but it's there for when all else fails. Support.
