Everyone kinda glossing over the fact that purging the servers would do literally nothing to the "short wait" OP notices on login. That has nothing to do with how many players are online, it's simply due to the login server processing in batches. You're still going to have a short wait to log in, and in fact, may even make the waits slightly worse by forcing more players into the login servers more frequently, rather than having them already processed and online on servers with capacity to handle everyone currently.
