Resource and item trading

hey there,
So I’ve had an idea I think that’d be a great addition to the game...
So I think it’d be pretty cool to be able to trade speedups aswell and possibly even jewels, though the jewels trading idea might not be something that’ll even be considered, but I think trading speedups would be a good idea, especially when you have big upgrades that go for a long while, and members can send you some speedups to help make it faster. I think this would b a great perk, but I think it should be only a perk that’s unlocked at a certain townhall so it doesn’t make the game too much easier or become something that defeats the purpose of jewels.
