As much as I really hate telling anybody to quit, it might be your best option to temporarily quit. There are a lot of other good games this month (south park - awesome, infamous, metal gear, titanfall, deus ex the fall, eso next month), so maybe give something else a try and then come back in a patch or 2 so that you have more to do. I have several friends in the exact same situation as you and that is what they are doing. Plus if you wait long enough the game will feel fun again, it seems like you've grinded all the fun out of things for the time being.
