How to fix clan war problems - more leader control
I have seen clan war problems in a few different clans now and have some ideas to fix them. These all center around giving the clan leader more control over the war:
1) allow clan leader to select a war roster - this would make it easy to bench inactives or people on vacation or unable/unwilling to participate for some reason, without having to kick them out of the clan
2) allow clan leader to assign or recommend targets for his team - this would help fix the problems with strategy not being followed, or people going for loot
3) allow clan leader to override clan members's war loot - if player do not follow strategy or go for loot, leader would have another option besides kicking them from the clan
These three ideas together could fix many clan war problems I've seen.
