1) More options than Opt in/Opt out. We need an 'Opt in if needed' option.
2) Clan members need to know when other members' heroes are unavailable. Currently heroes cannot be used in war when being upgraded. Its important for members to know how many heroes are down in order to decide when to upgrade.
I'm suggesting that players have an icon on their information bar for each the barbarian king and archer queen. If being upgraded, the icon for that unit would be dithered and have an approximate time until finished.
