In between running dailies and heroics on my paladin and my warlock, I'm still occasionally working on leveling my warrior. He is breezing through Northrend with ease. I'm working him through Grizzly Hills at the moment, where he just recently hit 75. Northrend really does seem to go quite a bit faster with the bonus to leveling speed as well as a couple of additional pieces of BoA.
I'm also about a day or two away from hitting exalted with Dragonmaw on my paladin which will hook him up with a nice new epic necklace for his healing set and a nice new set of boots for his ret / questing set. He's also pretty close to exalted with Hellscream, but he's going to need quite a few more commendations in order to get his epic trinket. I'm not in a huge rush on that, as he's got two good jewelcrafter trinkets equipped right now that seem to do the trick nicely. After that, I just need to finish getting to exalted with Ramkahen for some stylin new boots and then it'll just be working on the daily each day.
On the warlock, he's basically just in the daily heroic for valor points mode. I'm just a couple of days away from getting the T11 chest, and after that will be working towards the cloak and a ring.
Beyond that, I'm starting to think about which toon to gear next - still debating between the hunter and the shadow priest. The druid for some reason still runs hot and cold for me in terms of whether I find it completely irritating running heroics on him. Not sure why. I may have just gotten spoiled with the paladin having the huge heals to keep the tank up, that having slightly better AoE just doesn't seem to compensate much.
