There might even be mobs that are good for levelling, just because SE says mobs are not good doesn't mean that players won't find a way to level on mobs. Players find a lot of things SE don't foresee or didn't think would happen.
Also they wont be the same quests, because when asked in the presentation if you'd run out Yoshi said they'd be still plenty left over, so to speak you won't be repeating the same ones as much because some are one time only.
