I think the Clan Wars system is not good and could be better competitive wise.
First: wars could instead of giving a relative amount of resourses to the winners according with their two battles wins, everyone on the winning clan could have their Clan Castles fullfilled with resources (the losing clan could have 1/3 of it).
That would make Clan Wars less about farming and more about teamwork.
Of course the Clan Castle maybe would have to get a resource reduction.
