So the downside of accomplishing most of your goals far in advance of a patch is it tends to make you run out of things to do. So I'm back to PvP! I did a few battlegrounds yesterday on my warlock for the first time since 4.3 dropped in September.
I still need to do that one last Dragon Soul run on my warrior, but it's probably a couple weeks away before I really have time to get that done. He's at least geared for it now, so it shouldn't be too much trouble once I actually focus on it.
I'd capped my honor on the warlock before the end of the last season, so he was able to get a couple of pieces of the new season's gear right away.
We'll see how long it takes before I get totally frustrated with battlegrounds again.
