This is just my point of view on how vendors (specifically Crucible, Vangaurd and Drifter) should be more important. For Gear, make the vendors sell all weapons and armor with rotating perks at reset. And if we rank up make it where it was like Destiny 1 where you could choose between a weapon or armor package. Another thing that could work out well is bring more bounties like Nightahade but with armor as well.
I agree fully with this! There is an extreme lack of variety when it comes to weapon loadouts because Bungie has taken the minimalist approach to this game and only adding a new weapon here or there with a year one reskin.
