So I've had an idea with help from people I did a raid with, what if Bungie gave the gunsmith the ability to reroll perks for any legendaries you get from nightfalls,engrams etc. Maybe charge the player a strange coin or mote of light or a few ascendant energies/shards etc. Btw you can also reroll armour too! I would like some opinions from players and some suggestions on what you all think!
