Hi there can we have something say an allied clan say when a hopper leaves during war time or preperation we can have a back up someone from another clan to help us out that would be nice. It would help with everyone's problem, and also this would help out with my other idea as well as adding a clan counter in the profile me ue to tell how many times a clan memeber leaves and comes back, if they leave an allied clan to go to another allied clan there number would be green, if they just move around like a hopper that number would be red

I see no point in this what so ever.

This is not meant to be a troll answer, consider it tough love if I state the reality. If you are having hoppers leaving your wars a lot then it is you and not them that is doing something wrong.

Stop recruiting guys and putting them into war right away. make them sit out the first war after they join. Rarely does a hopper have the patience to wait like that.
