I agree about blade shards, chak eggs, mysitic forge stones, etc. I also suggest resonating slivers.
I undertsand why you don’t want to put crafted things in. Would it be hard to at least make more things stackable in the bank, like the various salvage kits, harvesting tools, etc.?
Every month I end up getting quite a few BL salvage kits. It’s great to get them for free, but it would be even better if they stacked.
It would be extremely hard, if not impossible to make those things stack.
