I've been going back and forth lately between PvP on my warlock and on my mage. I must say, the extreme control that comes with being a frost mage in some ways have me leaning more that direction than towards the warlock. I've just been having a lot more fun with the mage.
I've also been messing around with a variety of my other toons on the PvP front trying to figure out who to gear next. My warlock is in full bloodthirsty and is honor capped for the patch. The mage is also full bloodthirsty and is about a quarter of the way to the cap.
So, I've been debating who to work on next. I've been messing around off and on with the hunter, feral druid, resto druid, warrior, frost death knight. Also been wondering about either enhance or resto shammy or possible disc or shadow priest. Needless to say, nothing is really speaking to me and I can't decide who to focus on gearing next. Normally, with my propensity for ranged, I would say either hunter or shadow priest next. I tried the hunter a bit and it really wasn't speaking to me. Might give the shadow priest a bit of a spin next and see how it goes.
I also had a couple of really fun runs with the new warrior, so even though I tend to be fairly melee averse, I might actually go that way next. This is the extreme downside of being a leveling addict, is once you've got all those toons to 85, it becomes quite perplexing figuring out who to play next. Of course, it always gives you the option to mess around with everyone just a little bit, which is sort of what I've been doing. I even dished up a nice subtlety spec for my rogue, who is normally just my bank alt and played around with him for a few. Also incredibly fun.
