You know you can run through the content of the other races as well?
Just pop into the PVP “mists” area on your (H) Hero screen, complete the quick tutorial (if you haven’t already) and right in front of you is a gate to Lion’s Arch. From there you can reach other gates that will take you to all other racial starting areas.
I found exploring these areas and participating in a few events was enough to get help push me to the recommended levels.
