PVP server had experienced population explosions and worse lags,
here're some suggestions which may help on these issues:
(1). Ban accounts which change email registration.
--- Many account trades changed the registered email, but not of all.
(2). Ban accounts which farm(or sell) gold(or rank) in the game.
--- plz note many gold/rank/equipment trade had been done with real money in real life through some chat/communicate soft wares. they had been more tricky and difficult to detect.
(3). Lock new character setting.
--- it may keep the sever out of worse even though it couldn't make the sever better.
(4). Set the client to English language connection only.
--- If not, it may need more GMs to monitor some private non-English channels where as many players as you can image are breaking the experiences of this classic WOW.
(5). set new PVP sever.
---- If don't resolve the upper issues, it could be expected that the new sever will be exploded and experience what the current sever experience soon ....
BTW, stop being racist.
