As Clint Eastwood once said in Magnum Force, a man's got to know his limitations. I know I'm not a good player, so I've gravitated more to the support role for raids and strikes and the Sunsinger fits that bill to a T. Self-Res is a god send for us less skilled players and the extra grenades always come in handy, whether it be for mob cutting or against bosses. I enjoy clearing out the Vex Goblins and Harpies that spawn during the Nexus battles, while the rest of the team does their thing whittling down the boss and if I'm the Last Guardian standing it takes the pressure off of you big time knowing that should you fail in a revive attempt you've got that ace in the hole SR to pop.
