Actually I found Archeology quite fun to do lately. I leveled it up to 600 in the last weeks of MoP but with the new system, that you can have your own collection of Archeology finds within your garrison is really cool and I'd like to finish it some day. It's also a great way to collect the last treasures you might have not collected before. Other than that I'm trying out new garrison buildings both on my main (got the Inn now) and on my alts to see what they offer. But as I'm mostly busy with raiding and gearing my warrior I don't have that much time doing the abovementioned stuff but it keeps me occupied outside of raids.
