The thing is the mines weren't even always where they are right now on block42. The 3 different rocks were behind a petrol station on a gras area.

Also the fact that its not good for too many people is wrong. We had a full server back then when the map was even smaller. Sure it lagged but so does the map right now. Also it has many options to base.

Last thing: I don't really think its necessary having the explosions (except for the c4 maybe) on the server. When you want to equip the explosive it should just say "Explosives are only allowed on server 1." So skilled raiders have bases to raid, and for new people its much easier to base without getting blown up. This would also make the server feel more alive. The mutant area is great for the mayor for example basing in a little bunker in that area or a criminal mastermind cooking his meth and making his dollar in a hidden area.
