I think having safe rooms to be a bad idea. I feel this would have people staying there and spoil the game. I do feel that sometimes it is nice to relax without worring if someone will attack you. If there is safe rooms,have a sort of time code. like 20 minutes every 2 hours or something.
Also limit the rooms. I think 30 is a tad to much. Mabey a safe room located umm equally across the lands so one don't have to travel too far for it.
like one in archae. and one in harsha or one in the umm far courners like near mhun. something like this(my geography is a tad mess up.)
