If you're grinding at 23 then you're just flat-out not taking advantage of any of the content. I've had so many different quests and other things to do starting at the mid-teens that I routiunely have to make space in my Quest Log for new things- there's literally TOO MUCH stuff to do it all before you outlevel things. Or were you being facetious?
I really enjoyed the Azuremyst Isle area... very expertly crafted leveling curve, and everything is pretty. I slipped from 1-20 in no time, before leaving for the mainland. It makes me excited to get to some 60+ content. Too bad I've hit the mid-30's rut again. That's about when I quit my first run at the game, over a year and a half ago... but now I'm a hunter instead of a druid, so it should be much easier.
