Last night my wife and I got to do an Ulduar 10-man raid. It was the first time we were able to raid together for any length of time since we had our baby, and...it was probably a bad idea. Distractions + one-handed raiding (and not in the good way) led to a lot of unnecessary wipes and poor performance.
Also: the trash to XT was a really pleasant surprise, especially since you can not pull them until after XT loses his heart the first time. Oops. Patch notes can occasionally save your life. :)
But that's not about the meat of this post. We did Kologarn, and after wiping a bunch we finally managed to get the bastard down.
And...the mark of the unyielding drops.
I wasn't thinking about it much, and it wasn't that much of an upgrade over my Favor of the Dragon Queen, right? Plus I'm not raiding full time right now, so I'd rather not get a bunch of gear that others will be able to use for progression. The other tank (our normal raid leader) expressed interest, and I told him it was okay but not the best for me, and to go ahead and take it.
Except...that basically is the best in slot at this time. Sure, you could go for the Bronze Pendant, but any other tank should get it before you do and it wouldn't be that big an upgrade. It's essentially equivalent to Boundless Ambition in most ways. Which means that if you have Boundless, don't really bother getting this...
But if you don't, you should probably pick this up.
Which is what I actually wrote in the previous gearing article for Ulduar.
And it was a sidegrade to the warrior too. So I just passed up essentially the BiS neck piece because I can't remember what I wrote.
I'll have other opportunities to get it, and it's still not that big a deal one way or another, but man do I feel like a dumbass.
