Basically a new clan troop storage that enables you to collect or donate troops.
1. You can only donate 5 troops every 20 minutes
2. You can only collect 5 troops every 20 minutes
when donating or collecting troops it would count as donated/requested troops count. (so you can see the donation/request ratio)
as for everything else your clan can decide how it should all work or whether to use the clan troop bank at all.
