I'd be curious to know of the people who gave level 20 answers, how many people started at level 20 and/or sped up leveling to get to level 20. I'm not saying that's bad or anything, just that in my own anecdotal experience (FWIW), people who play up to end game levels prefer the end game level, so they get there as fast as they can. A lot of the PC builds people are like this, it seems, since they love making maxed out level PC builds and want to see them in play.
