I get it. There's sentimentality, those of us who enjoy collecting,etc. Honestly, for me I don't like deleting weapons because some of the older weapons with unique rolls still shine. The tier boost doesn't do that much in reality, the real reason they feel better is the featured gear buff. But what's really eating up my vault space ATM, is exotic Class items and ergo sums . Really wish these were craftable items.

I wondered about the tier thing, I don't notice much of a difference either.
