on my warlock i use him a bunch in strikes as either a stormcaller or sunsinger, and use the light beyond nemis or heart of the praxic fire. Light beyond because it generates more orbs, and the praxic fire for HELLA grenades and melees while in radiance. I use radiance offensively instead of as the ability to res. stormcaller i just use super when there a bunch of dude, majors or ultras or lower ads, since i use the ability to bounce the lightning to like 4 or 5 targets instead of one or 2.
