New (Maybe) Shield Idea

Not sure if this was ever proposed but here's my thought.

New 2 hour shield that can only be bought once per 24 hour period. Attacking multi-player does not break this shield. So if you buy today at 2 PM, you cannot buy it again until the next day at 2 PM.

Having to keep your session going is pretty annoying when trying to save up for an upgrade. You should be able to do other things while waiting for your troops to cook.

No. The only purpose of the shield is to protect you when you are not there, not when you are there. If you want a clear session of farming, then don't log out until forced by the system (at 6h of activity). Having a shield active while you are also attacking is unfair for those who you attack.
