Having the game's difficulty increase as time passes on a server seems like a really bad idea . . . new players who join shouldn't be facing mobs with diamond level gear while they are still punching their first tree. Not only is that unfair, it gives a huge advantage to players who join the game on day one.
This problem goes away completely if I can match raider difficulty to the game stages a player has unlocked in my pack . . . I have no problem giving Raiders flux charged swords and power armor when they are facing a player who could/should have equivalent protection.
Could I please have game stages support? It would make a huge difference! :)
