I don't pay attention to level in GW2. The real limiting factor are skill points. The only time level becomes blatantly obvious (to me) is when I progress too quickly in my personal story.
So much of GW2 is how I would have designed an MMO, so I find it interesting their original intention was not to have leveling because it's something I wouldn't have had either. Kind of a shame they changed their mind, I would have liked to have seen how it worked out in practice.
