If this system for base raids had been referred to as "Fair Warning" or "Showdown Challenge" or "Red Alert" rather than 'appointment', I don't think there would have been such a strong negative response from some.
GreyDog said it well; this CAN be fun if the it is represented in a fun, creative, comics-style way. "Lord Recluse" was correct in his original statement, too; this will only be fun if people participate. And everyone who said, "Let's not make this an issue of perma-camping the base in the off-chance it gets attacked"... AMEN.
