You can't edit the drop rates at all because they are percentage based not multiplier based, you can change the drop rate to 10000000000000x drop rate and it will still be 1x when you actually play the game.
So drop rate means NOTHING. If you actually played the game you would know that.
Right now this is the only private PW server that doesn't have cheating GMs/Admin. That makes it the best out there.
