Idea for the game - Clan bank
I believe that this idea has many things that would need thinking about but once done would be a great asset to the game and many players. The idea of a clan bank is that each day you can send a percentage of your elixir, gold or dark elixir to a 'clan bank' only a small percentage could be sent daily so then you are unable to send everything therefore if your village gets raided there is something to loot for the attacker. A clan bank can naturally be accessed by anyone in the clan and only a small percentage/amount could be taken out daily (the amount and percentage could be determined by whether you are Elder, Member or Co-Lesder therefore adding more value to the clan ranks). Although the clan bank can be accessed by anybody in the clan new members will have to wait at least 3 days after joining (Or more haven't figured out the perfect time span) before accessing it so therefore no hoppers are able to simply join a clan and steal resources. Members of a clan could also possibly be banned from using the bank by the clan owner if he sees fit, this would be a good idea for 2 reasons: 1. Clan owner can give members access to the bank depending on their contribution to clan activities (clan wars/games) therefore motivating them to do better, 2. If there isn't a fixed amount of time after joining before being able to access the guild bank the owners of the clan can decide for themselves how long they want newcomers to wait before using it.
That is the end of my idea, although I believe some improvement could be made to it I believe it has potential, hope you have a think about it and give a thought through answer.
