Alliance members kick or leaving after placement
Since you are working on improving alliances war/quest, I have a suggestion.
Forbiding an alliance to kick someone, or a member to leave, after that member has placed his defenders.
When you have a member, who has his champs placed has boss/mini, leave when attack begins, it's very annoying.
I don't care if the player don't fight in attack, but, at least, you still have the defenders.
