My guild has kind of fallen apart. We don't do 25 mans at all anymore. We just have a few 10 man ICC runs a week. I'm lucky if they coincide with my schedule. I haven't done a clean run of ICC in 2 weeks. Just brought in my mage to help dps once when they were stuck. I gave up on thinking about my warrior's set bonus and just bought the offset tanking gloves. So he now has the Frost badge gloves, belt, and cloak. I'm going to replace his Onyxian blood talisman with the Triumph badge glyph because it will be nice to have the extra dodge. I feel like I'm sinking a lot in to getting him to the point where he could tank a good bit of ICC 25, if he ever gets the opportunity.
Also, in looking at the set upgrades for tanks, a lot of them lose a bunch of defense rating, to the point where I would have to get to get back to 540. The two piece bonus is good for threat, but I think I can remedy any kind of threat problem by just getting non-set gear and doing more damage. He's unlikely going to get the set bonus as he just doesn't get enough frost badges (as a result of not going in to ICC every week).
Here's his armor if anyone's interested.
