I have three ideas to propose :
1 - In the Clan War some Clasher doesn't participate it would be useful for the Clan leaders to have some additionnal informations on the ''my clan" page (maybe next to ''troops donated / received") such as "number of attacks"; "stars winned".. to know the Clashers that helps and the onces that doesn't.
2 - It's somekind of Clan War but with a One2One versus, each Clasher attacks the other three times and the one who wins more stars wins the game, if there's a Draw another round is allowed.
3 - Sometimes we loose a battle against some Clashers 'cause of technical error (connection lost, Smartphone / tablette bug's...) and we like to have another chance but we can't
Hope see one of these (or all of them) realized
