This can be a little hectic if you're on a PvP server since most level 50's are in this zone, but that's for a good reason.

Allied races aren’t much better. You can only earn them by grinding out reputation. It doesn’t take that long but casual players will need to invest a couple weeks primarily to it, and focusing on that grind will take you away from others, like earning gear. Each race has its own grind, but the things you do to work through it remain the same, adding to your boredom.
Be cold-blooded about admitting that you've taken a bath on an item. If you bought that sword for 5g, listed it for 10g, and the listing cost is 2g50s each time, after two times it had better sell just to break even. Once you hit that point, don't keep listing it over and over in desperation trying to make something off the AH. D/E it, or vendor it, and move on. Lesson learned. Don't get trapped in the fallacy of sunk costs.
