How about having an specific building the whole clan can access for troops. Let me go into detail, This would be like a area kind of like the clan castle, but everyone can access. Put a troop limit on it & everyone can donate troops anytime unless full. That way if you need troops people can pick and choose what troops they want out of it, first come first serve. A clan can also make a rule of what kind of troops they want in it, kind of like an army reserve.
