I have been thinking of this idea for a while now and thought I would share with you guys. I think you should be able to choose which members you can take into a clan war with you. Just because you have 20 members doesn't mean that you should have to do a 20v20 clan war. What if you want to just do a 10v10 because you know some people won't be online. Maybe some clan members are having trouble with their attacks and you want them to practice and not have them hold the rest of the clan back because of their bad attacks. Basically I think you should be able to choose your size of clan war that you want to do.
