You know if the pvp community are forced to leave the game a lot of people will be wanting their money back. ED and less players = Bad for ED
Thats why the shadow server exists. The whole I paid for the product but can't access it anymore argument falls flat when they can still play (on their own without being able to change anything at all).
I don't see how the PVP community would be driven away by anything though. Griefers might find themselves getting lonely, but thats to be expected.
