A partial fix for players leaving clan during war
Open clans have a problem with players who leave during wars without attacking. A proposed suggestion was to not let players leave during wars. This was shot down because it would be difficult to leave a clan that wars constantly.
A better idea is to only allow leaving on battle day, and only after the player has used both of their attacks.
If SC did this, some players would try for stars since they have to attack anyway. Other players would just drop one troop and leave. Still, since some players would attack who otherwise wouldn't, it would be an improvement over the current situation.
