Wonder if more of the players history information can be part of their profile. How many wars they have been in while in that clan and how many stars they have gotten the clan in the wars they have been in (or average).
Of course something like this would reset when they leave/ join a new clan.
It'll be on the same line with how many troops they have donated and how many attacks and defense they won.
Just something to keep an eye on progress of a clan on... to better the clan.
