How to play WoW tomorrow (if you main on ultra full realms)

In your config.wtf file in your WTF folder (while WoW is not running) you can add this line at the bottom:

SET disableAutoRealmSelect "1"

This lets you pick a working server without the game forcing you into your normal main server. You'll need to put this in before every time you boot the game up though. You can open up this file in any text program - make sure to save or rename it as a .wtf file when done.

Why it's about to be important: when BfA released, big servers crashed, but many servers were fine and said the launch was the smoothest ever. However, the game conveniently auto selects the last realm you logged into. That's a great feature...when your realm isn't on fire. However, in the event of a very hyped expansion releasing on a holiday week, it's likely that a few servers will be burned and it's very hard/impossible to navigate away from them when they are auto selected.

I'm basically reposting this tip now for it to gain traction. This is how you can navigate from your mega servers (Illidan, area 52, stormrage, etc) to be able to at least do something on lower population realms day 1. Every character has to go through the maw intro questline, so if you've got level 50 alts on other realms, you might as well do that intro on those alts while you wait for your main server to come up. Or even level all the way up to 60 so that your main can just skip around the shadowlands when it's playable.
