I remember doing Crota's End once and there were a couple people who went crazy over how useful it was when I used my radiance, plus 9 orbs most of the time. Made me feel special, especially since fireborn is useless if you aren't dying too much.

one time we used Solar and Vortex grenades to force Valus Ta-auric into a corner and then he was forced to take max damage from the grenades. died in 30 seconds with almost no heavy weapons used
