Yep, it's overwhelming to say the least. I suggest that you pick one thing and stick with it. In the past it has been epic mounts, attunements, rep, you name it. Since I have done all of the quests so many damn times, I decided to make it about pvp gear. I'm about two weeks into 70 and I only have 4 more pieces to go! Soon I will have more time to quest / do dailys, yadda yadda.

Once you get one aspect of the game to a point you are happy with, switch focus to the next thing on your list.

Just slow down and enjoy it. Grats on 70x5.
