Jezebel
I played this game when it first began on Facebook and I played for several years as a lone wolf. I have only recently returned. I don't change my name and there are still some here that recall my gameplay way back then. I learned a long time ago that brute force may win battles but it does not win wars. I win wars.
I agree with the moderator .... anyone can attack a fief if they are willing to pay the price for doing so. Attacking one of my fiefs comes at a hefty price. I doubt the person who did thinks it was worth it now and I'm quite sure his Marshall does not. Anyone can attack anyones castle too. Because everything is fair game. Your castle, your fortress, your fiefs, your fellow league members are all fair game. The real question becomes "is what I am about to do worth the effort".
They pretend to laugh about it because it is humiliating to them as it should be. They haven't damaged me at all. On the contrary their behavior has strengthened my troops, helped me level faster, and earned me a considerable amount of sapphires. I can't even count how many times I have set their marshals castle on fire for all to see. For me it is a no lose situation.
