Well your doing it wrong. I was too then I read up and used strategies to level up. It is night and day diff. Just loaded up the new expansion and with in about an hr I had most all my stuff up around 605-608 because I researched what bounties to save and then cashed them all in and got many powerful rewards before even playing. I consider myself a casual but a smart one. I use a lot of methods that hardcore guys use to help me keep progressing.
