Save your army...

This trict I learn and big helps to avoid the attacking to your city. When you leave your game to bed or to work, don't leave them in city by themself, Use them with your hero go far away to plunders . (Do math is you leave games like 12hours so choose location 6 hours away send troops and hero go plunder so plus time they comming back is 12hours that you gone ) Doing this exercise help save them while you gone and get bonus resource when you log back in games. Now happy plunding. If your city under attk while you gone your troops still on hands easy for turn back use for fight...
