I have gotten to where I now carry guns for a few builds for that character in their inventory and storage is where I keep mods/relics only/grenades/shields. This frees up space for transitioning weapons between characters. The legendary’s I have that are not viable to my characters started to go in the trash dump. The reason I started to do so is because the leveling gear are not much important when you find good guns often and out level them fast enough anyway. When they raise the level cap, most these are going to be trashed anyway and we will be re-farming (not as fast, but the paced scale they intended) by that time we will be having more bank space anyway.
Just wanted to give a new perspective and not all will agree with me, but hopefully might help a handful of hoarders looking for advice, from one hoarder to another.
(and yes I am a self diagnosed hoarder, my track records in games can support this)
