I'm a big supporter of PvE servers, and I like to see more of them. But I do not see the server survive in its current state and with recent events on its own.
Personally I don't mind playing with "only" 100 people on a server. Gives you more the feel that you know most people around you, just as we did in the "good old days" But I'm also realistic and I know it cost a lot of money to keep things going as it is, and also alot of extra work for staff members. And some more stuff but I'm just so tired..
In conclusion, I think the good does not outweigh the bad and the plug must be pulled.
