Leader choose who participates in war
I think leaders should be given the ability to select who they wish to participate in war, this is a good idea for two reasons
1) Sometimes members are away on vacation or cannot play the game for some time for whatever reason it would not make sense for said player to be part of war when another member who may have less trophies can participate.
and
2) Sometimes a new member joins my clan just because this new member has more trophies should not mean that this player is more eligible for participation in war than a loyal member who's been with the clan longer but may have less trophies.
I think the leader of a clan having the option to select war participants is a much needed feature and I hope to see it added in the near future.
