You have your opinion. Xsyon himself already said no. Can we move on? Same topic, said the same way.
"I want" is your reason. Xsyon doesnt. Xsyon wins its his game.
You can say it will bring more people. I can say it will cause people to quit. There is no data to support yours, and none to support mine. They are opinions. Xsyon clearly has an opinion also. He said NO, to flags, and NO to a PVE server (at this time).
You use words like "should" well guess what, that's your opinion. Mine says it "wont". On top of that, to do something like that would take time away from the devs doing more important things like, adding content, fixing bugs etc.
