But you can fight/camp there. You only have to take some anti-radiation stuff. Or do you think that it is impossible to get some in game? Or do you think this will be too much griefing for PKs?
PKs? Are you saying it should be a guarded HQ mine? If it is unguarded, then, yes, there are going to players that most likely will kill you. That's just how the game works.
My point was that the inside would be irradiated to prevent people from spawn-camping the mine, but the outside should still be unguarded to still have fights around HQ materials. All I'm saying that if a two-part (Inside has Materials, outside has spawn points from World map) mine map is used, then the inside should be irradiated so people can't spawn-camp the one or two entrances. (To answer your other question, I doubt campers are going to take Rad-X/Away just to camp a mine entrance, so that, again, wouldn't be a problem as far as camping goes.)
Wichura's map seems to be an open (outside) HQ mine, hopefully with multiple spawn points so that people couldn't easily spawn-camp the zones, then that wouldn't even much of a problem anyway.
