When you start a world and have set rules for that world its like signing a contract with the players who have the right to play on that world or not based on those set rules. I am one of those who do not like FA attack servers so i don't play there. The information provided allowed me to make that choice.
Changing the rules without consultation with the players, after the fact, takes away those choices is kinda like a breach of contract in my mind. Leave things alone on set servers. It screws things up for the players.
This is not how to please your clients, this is total crap when developers decide what they think is best, without putting the client first.
We pay your bills, remember that!!!! Its really important for you to not piss off the hand that feeds you.
