This * ruins about 1 out of every 3 wars we get into:

There needs to be a cumulative points accrual for people not under shield, or a cumulative points loss for teams that hide under shield the entire match. We have a 25 person team that is very active, but if we aren't running the game in a 24/7 operations center it is possible for a team to take a slight lead and hide for 36 hours.
This current war WE took the lead and forced them under shield, they stayed under shield for 12 hours - a few exited in the middle of the night and somehow snuck the lead.... anyhow, we have 25 bored/angry players because there is no recourse, and this is happening frequently enough to turn people away from the game.
