Last week, we saw patch notes for the PTR and patch 4.0.6. Since then, we've seen updates to these notes. These updates mean that some of the things we talked about no longer apply. And then they went and updated them again. It would be fair to say I kind of groaned when I saw Blizzard do this, knowing I'd most likely have to basically spend another week talking about the notes. I was especially annoyed because I finally have my tank set to the point where I can tank in a raid or a heroic without feeling painfully undergeared, and I've gotten my DPS up to where I think it should be at the current gear level and talent spec design.
In general, I think warriors are almost where they should be right now. We may be slightly weaker than I'd like as tanks, and arms is frankly pretty bad as a DPS spec right now. It's still good for PvP, although that's mostly due to its ability to chain stuns, which it will be losing somewhat in 4.0.6. With Slam still not scaling at all with haste, arms is going to need flat-out DPS increases to go along with the nerfs it's taking. Fury will probably be all right -- not the absolute top DPS, even among hybrids, but it will deliver in fights where melee is unduly punished for being melee.
So let's go take a look at the cards we're going to be dealt in patch 4.0.6 as of the most recent update. If I had to sum up the entirety of the remainder of this post, it would be, "Okay, but why not buff arms for PvE?"
