The wasteland is not harsh. The people in it are harsh.
If you fast relog and shoot another player in the first 3 minutes your character should turn pink or something like that to mark his shame for fast relog in PvP, that way everyone can still do it but your respect will go down and in videos or screenshots it will show how many people just keep fast relogging.
varandas, the largest drop in the number of players happened when crafting became the primary way of getting items instead of farming.
Heck, I'd risk saying that if the devs removed all the "exploits" like 5mm steal-farming etc. the server would be pretty much empty by now.
Crafting is ok for people, who have one character and 100x 5mm ammo is wow for them. Sadly, for pvp apes with a great ammo consumption (one ave-burst is 40 ammo, player carries 400-600 ammo to every battle) this current crafting system is unacceptable. They would have to spend an insane ammount of time doing something very boring.
