I pugged the first half of Kara last night (Monday).
It was GREAT!
It's billed as not a quick badge run, but rather a first-come-first-serve roster to get people some free gear before the reset. And get gear we did - two upgrades for our hunter, one for our rogue, a DPS ring for Kante, an offspec sword for the holy pally, and Tier 4 gloves and the Eternium Greathelm for yours truly. We oneshot Attumen, Maiden, and Curator, took a second try on Moroes due to CC confusion. Other than that, it was a lot more cohesive than some guild raids I've been on. I was impressed.
I've been doing a lot of reading on Tankspot.com about Effective Health Theory, so I'm following it when it comes to gemming and enchanting most of my new gear. The gloves are going to get 15 agility to be part of my slowly-accumulating threat/avoidance set, the helm is getting straight 12 stam gems to make it more EH-friendly, although matching the socket bonuses would turn it into a good avoidance piece as well. I'm going to continue stacking stamina in the immediate upgrades I get until we hit up 25mans or Wrath of the Lich King is released - I was given the MT position in tonight's raid by sheer virtue of having almost 13k health unbuffed, where the other warrior technically outgeared me (several epics, no green gear, all enchanted) but only had 10k health.
Food for thought while I'm at work tomorrow - What badge piece do I want to pick up first?
