Not that I don't have any. But I suddenly stopped getting it. I was trying to get the access key for Rogers Way in Southard. After I spent the 15-20 minutes killing over and over, I noticed that I wasn't getting any experience at all. I relogged a bunch of times and it's still not working.

Customer Service is closed today. Any help?

Are you fighting NPCs who con gray to you? You won't get any XP from them.

You also won't get any XP if you're level 50 and have maxed out your XP meter.

I didn't know that. And I meant to mention I'm getting exp from missions. I'll try it out with non-gray NPCs.
