[2020] A genuine question: literally what’s the point of the collections tab for weapons and armour of you can’t reacquire 80% of it?

Like yeah, you can pull year one stuff with certain rolls, like midnight coup from Levi, or maybe the old trials of the nine weapons if anyone still has those, but everything post forsaken can’t be taken out from collections unless they’re set rolls like Vestian Dynasty.

Am I the only one who doesn’t see the point of collections behind a) being a glorified checklist, and b) for sparrows, emblems, shaders and the like?

Edit: laid down for a nap and my phone exploded, thanks. A couple people brought up a really good point; how would collections work with weapon retirement? That seems like a pretty big question to be asking
