People getting disconnected from too many people being on the servers? You know you've done something wrong.
Fix it now, please. This should never have been a problem. Hardware is dirt cheap.
Its not that too many are fighting its that the limited amount that have paid for this joke can't even get in. If that really was the biggest problem I'm sure there would be more servers. Even cryptic knows once the free month expires 50-75% of the initial players will be gone.
