What's the fastest way to level?

Whats your definition of "foooooreeeeverrrrr"?

I took me about four hours to hit lvl 3, and probably a solid fourteen hours to hit lvl 15. Granted, I wasn't very familiar with the areas before, and was still getting used to using a controller, but it still felt like an awfully long time. I think I made the mistake of purely following the city-quests, when I should have just ventured out.

Anyways, I've been slacking-off the past couple of days, but I'm hoping to really get back into it today and this weekend. I think I'm lvl 28 right now, hoping I can hit lvl 40 by Sunday night. From what I gather, I should just focus on the Story-quests until I get to an area with enemies the same level as me, and then also run Side-quests. I'm curious, though; is it worth queueing for Dungeons while I'm questing? Or *just* focus on questing?
