I think Clan members should be allowed to donate resources to each other to help each other reach upgrades faster, repair traps, etc.. There would be a cool down time on that type of request (about 4-6 hours i was thinking). The donations would go to the storages, not Clan Castle, and also be fair game for attackers to steal. Members would be allowed to donate up to 5,000 units of the gold or elixir (depending on the request ) or up to 2,000 Dark Elixir. The stats of donated and received amounts would be shown on the clan page. I feel it would be a good addition to the perks of being in a clan.
