Lord Thane on the bright side you know where your castle is, and you have the odds stacked in your favor to get it.
Let's take a look at this "odds stacked in your favor to get it".
Hypothetical scenario.
Two kingdoms, with 100 land and 4 castles that are the exact same KS, but one of them is wiz fat and has a weaker military. Kingdom A more military strong attacks Kingdom B and wins. Kingdom A now has 24 hours of protection from anyone other than Kingdom B. They are 125 land 5 castles. Kingdom B is now 75 land 3 castles and has 15 hours of protection. So hour 16, they say screw it, and send whatever they can against this kingdom that has 66% more land (and production). They win! They get their castle back! Oh no, retals don't give CLI. Kingdom A has 15 hours of protection. Now, Kingdom A has two quick options. Tell someone, hey Kingdom B just hit me for a retal there's an easy castle for someone to get. Other option, wait 8 hours and hit Kingdom B back as soon as their army gets home. I think the more likely scenario is that Kingdom A has rebuilt a strong enough army that kingbom B will bounce without a pre, and their army will be crippled again.
