Currently the clan war roster is automatically set. Even if some players cannot participate they are still included. If the players with low trophy count want to play they have to increase their trophy counts and bump other people down. We need a viable solution to these issues.
Allow each player to opt out a clan war and for leaders to select which clan members are excluded in the upcoming war is the way to go. This can be done by implementing two switches. One switch is set by each player on its own profile that determines if they want to be in the next war. The 2nd switch is set by clan leaders to specifically exclude a player (could be an addition button next to promote/kick). Only players who have opted in and not excluded by clan leaders can be part of clan roster.
Additionally leaders are allowed to select the war roster size to any number possible. For example if a clan has 23 people that opt in the war and are not excluded, the leader can choose to start 10, 15, or 20 member war instead of the maximum number possible.
A system needs to be in place so clan castle troop donation can only be done between the war participants so the game can be fair.
These features will make war experience a lot better.
