Still considering this idea, new layout would be fresh, the old castle are getting boring, the pront one has been opened for 2+ years, the others for at least 1+ year.
My main concern is regarding the guild holding them, whoever gets their castle taken from them will rant. Sooo.... I'll turn the question the other way. Who wants to give up their castle?
If you're a guildmaster and you own a castle you can pm me about it, you will lose their castle entirely on the day of the next woe, I'll open another in the same city and it will either be empty (monsters + mvp) or be defended by the GM team
Only 1 change per town obviously, we wanna enjoy the new castle for some time, wont change it again for at least another year.
