Another new player's experience:

I love that this game allows me to have my life, and still come on and get some decent progress in leveling in a relatively short guildleve period. Yeah, I know, I'm not playing it "right" to blast through content as fast as I can to superfastultrahurryfasterfasterfaster to level cap, but I've, as a new player, gone in and personally experienced all the low level content I can find, and I'm loving this game.

I think the problem is the mindset people have that they have to hurryhurryhurry to level cap, and don't go and experience content for the sheer joy of seeing/experiencing something new.

tl;dr: The problem isn't the content available, or the game design, the problem is player mindset.
