Asherons Call: QotD - What Would You Want in an Expansion?

Let's pretend that umm, next July we're getting an Expansion Pack. (this IS fake guys...no posts on the Vault about an expansion coming, ok?)

What features would you want? And remember, doing things like upgrading the graphics engine will make it impossible for people on older systems to play.

So, think...what do I want that's BIG, NEW, EXCITING and I'm willing to pay an additional $10-20 for?

(yes, I'm annoyingly sarcastic today)
