Firstly we all have real lives and this take presidecence over a game
but in reality we also put many hours into the game, and whether you spent money or not , but just work as hard to build your castles up.
so to stop key sharing which i think is prolific in this game, because of GGE flaw in there game, ie people need to work and sleep, but the game is a 24 hour game.
And no matter how smart you are at defending you will burn when you work or sleep.
Also i believe if the was no way to share keys , many many players would have left by now , why would you want to do that hard work just to see it burnt away.
So i suggest a sleep mode for 12hours so when your offline .so when you start to play again you can at least ask for help etc.
to stop misused when you start sleepmode you cant turn it off so you wait 12 hours befor you can play again.
I know there are fire casts, but if war has anything to go bye , they norrmally send a fire com , maybe GGE may not want this button , becase it cost 10k rubies to repair.
this is just a suggestion , maybe it could be improved on , or just to be shot down as a folly
