Well we both know the biggest drawback to the Angel of Light perk, and why so many guardians don't place it in their load outs, is because the Angel of Light hover duration only allows you to register one or two good shots before it abruptly sends you to the ground. If there was an exotic that extended the duration, I believe we would see Destiny players employ this perk more often. No icon is more of a Sunslinger trademark than seeing a winged Warlock on fire while in midair, off in the distance, yet we rarely see the Angel of Light.
