As someone who likes to use weapons more than abilities, I've always wanted there to be an exotic piece of armor that's exotic perk allows for a guardian to have more than one exotic weapon equipped at the same time. I would make the exotic be the only exotic piece of Class Armor in Destiny 2. Also, due to the immense power this exotic will allow for, it would have a penalty of -10 to all stats and would increase the cooldown of abilities and super by 25% if you use 2 exotics, and 2x that if you use 3.
