I'd say wait 2 weeks to see if Alexander Savage isn't the challenge you're looking for, and if it's not then maybe it's time to take a break for you. The thing about burnout is that you need to know when to stop and put the game down or you risk ruining it for yourself permanently-- speaking from experience with other MMOs. It's frankly better to set a game down "for now" than to burn yourself out so hard that you never want to touch it again.
