Blizzard PLEASE Make a Clan Stash

i am just curious if Blizzard ever thought about creating a Clan Stash…. it would kinda fix the Rune trading aswell as giving other players Assistance such as Items

Also it would be actually a good Improvement in terms of Clan Organisation > Donations/Rewards etc.

i think it even would keep ppl in the game for longer not only the first 3 Weeks a Season comes out and everyone leaves and waits for the next one
