Have you done all the story quests and class quests? Currently, there's also the 'egg-hunt'. How about helping fellow LS mates get their classes to 50? Or maybe even get creative and do like a scavenger hunt, go exploring, or do like an aetheryte field trip, to help out folks who are new to the game.

Or you can keep choking your chicken in uldah as you say, wallowing in your own self-loathing. It's up to you.
