SimCity war shield time limit - 4 hours

it seemed like a good idea but it’s not.
Our club has now had 2 wars were the other team did the same thing. They didn’t engage they just repaired and stocked up on ammunition. Hardly attacked. They lurked and waited. When we had them all under shields they let the clock run down to around 1 hour then repaired. They would test who was active by little hits against cities to see who was active, Eventually our club had to sleep (we all have lives) and even though we are across a number of time zones eventually they got us. In both wars we were over 40,000 points in front and with over 10 hours of the war clock to run we got timed out for not repairing (at least 5 of the other club members had shield buster weapons). Our club has resolved not to war until there is a change to this rule. For us it’s a waste of time and effort.
