So I've been playing Destiny 2 for about a month now and I started a new character just today. Pretty much my question is this: what exactly can you do or not do with Collections? I've read things saying they track and allow you to duplicate all the items you pick up that have set modifiers (no random rolls), but in making a new character I noticed that the size of the Collections tab itself is different. While I had a page and, say, 5 items in the SMG tab on the my hunter main, I only have a page and 2 items with my new Titan. Also I just picked up a single shot grenade launcher and it definitely isnt in one of the 4 slots of the Collections tab. Does the Collection really include EVERYTHING I pick up or is it just legendaries and (some) rares? Any helpful info or links to things I may have missed? EDIT: the grenade launcher for example was called Resilient People. And it wasn't in the Collections.
