I do hard raid. If the team starts tripping up then we either recover or wipe, then learn from the mistakes. You don't learn anything if a self-reser saves the day (except "let's all rely on the self-reser. We don't need to be good anymore!"). Actually, both the Sunsinger and Titan can significantly increase a team's DPS. Song of Flame allows a team to throw out 6 grenades a second, and Weapons of Light is a near-25% boost to damage output on every shot.
