I still have to complete 5.4 MSQ, haven't even unlocked Emerald, still have not found a group capable of clearing Seat of Sacrifice EX, and the new role quest released in 5.4 is also collecting dust on my end. And I don't even touch savage, which I would imagine prog groups would consume a lot of game time if I did do them. I do log in most days, and I'm just working on other things that have my full attention currently.

If you can't find things to do in the game outside combat, your experience will get stale very quickly. If you do want more combat and you are not doing savage/ultimate, then the answer is right in front of you.
