Guild Wars 2

Just came to me that there is a solution to a lot of crap that fills up over time. Items that are account bound for whatever reason or at junk status. Add a wildcard option in the guild halls material storage so you can say add 100 blade shards (just and example) and get 10 of some item you need in the guild hall. Or a 1 to 1 ratio, would be good either way.
Benefit is getting some items going faster in the guild hall while removing un-needed items without destroying/throwing them away.

This is a pretty interesting idea I think.
Even though some guildhall materials are very specific. like insignias or runes or lodestones.

For the simple materials with huge amounts this could definitely be a thing.

It would probably require alot of balancing work though to see what works and what would be a fairly unfair conversion.
