I’ve always LOLed whenever I see this complaint in chat. There are plenty of things you can do while escorting, but if you feel your time is too valuable then that’s on you. Most players who refuse to escort never really stop to think about the actual loss of resources by not escorting, which is easily several thousand basic resources and up to hundreds of rare gems daily. Also as someone else mentioned the majority of wagon thieves are from smaller kingdoms who NEED those resources from the guy who just spent 3 minutes sending 20 wagons back to his city.
"Plenty of things to do" there is only one thing to do and that is to stare at your screen and wait for someone to come and rob your wagon and take out a couple of your troops and heroes. Then repeat again untill you have spent a couple hours each day just staring at your screen... waiting.... so fun and interactive gameplay i must say.
Atleast if someone stole it and there was a system in which you can take back the stolen resources we can strategically choose targets to rob and not to rob instead of just... staring at the screen... waiting...
