I finally got the rest of the frost badges together for my fourth tier 10 piece thanks in part to the holiday boss rewarding two each day. I ran around to gem and enchant it right before going to tank for my guild's weekly raid.
It was better than I had even imagined. No more did I have to worry about timing my enrage with the readiness of the raid for maximum rage at the time of the pull. Enrage was always a little weird in the sense that you want it for the start of a pull, but you don't want to take additional damage, especially at the start of a pull when healers are getting into place and hots haven't been stacked up yet.
With the set bonus enrage is actually another defensive cooldown with a 12% damage reduction instead of an armor reduction. So you can enrage as you pull, have plenty of rage to get some decent snap aggro and at the same time take less damage while healers get situated. As an added bonus I have a talent point in King of the Jungle since I run with a hybrid tanking/DPS spec. That provides me with an extra 5% damage while enrage is active and helps even more with getting a good lead on aggro from the start.
In the middle of the fight the rage or aggro aren't usually an issue so it becomes a lesser barkskin cooldown to reduce incoming damage. There are fights where it helps more though like Bronjahm in Forge of Souls. In phase 2 he doesn't hit very much and rage goes to near zero pretty quick, popping enrage allowed me to put out a lot more damage than I would otherwise been able too without taking additional damage.
Speaking of Forge of Souls I ran that after my raid as you might have guessed, and guess what dropped off the last boss! The Needle-Encrusted Scorpion, of course. I can't even remember how long I've been trying, but I've lost the roll at least 5 times and some days I even got lucky and ran it twice, once queued specifically for it and again after as a random heroic.
I must say I earned it that time, healer went down in the beam (which happens quite often) and I took the opportunity to battle rez. I don't think they expected it as they didn't accept right away and I had to resume tanking before I could top them off with an innervate. Blew a couple cooldowns to mitigate the Phantom Blasts in the meantime, if only I could lower the cooldown of bash further or convince PUG DPS to interrupt. Boss went down and I won the trinket, yay. The 22 slot bag dropped that same run, but I didn't win it, I'll just equip the crafted 22 slot bag I made on my rogue as a contingency plan since as I suspected I don't want to run through that instance again for quite a while.
