Well I thought it would be a shame using sunsinger for that strike cause of the void burn. I do use warlock sunsinger most of the time because I like the force field extended range melee and the double solar grenades. I must of been doing something wrong cause I thought I would be rockin with the vortex grenade and nova bomb - but many times I died before being able to use my abilities, which is what got me put off about it compared to being a titan or hunter in the same situation.
