I mean to be fair, I have nothing to do either, aside from playing gauntlet and I am in SSS slowly working my way through. But that is the point. You shouldnt need something new to do (or something new you feel you HAVE to do in order to keep up) every single day. I wouldnt mind a few days a week where all i do is skull quests, daily achievements, daily dungeon, run my troopers, close the game. Its nice to have that option every few days. Also like others have said, just play around with different talis and characters to test them out. I've barely ever done that, always chasing some carrot, never any time to enjoy the taste of it.
