My guild doesn't have a 100% dedicated MT, it cycles between myself, another DK and our GM (Warrior) depending on who can make the raid. We have all MT'd all of Naxx 10/25, blah blah blah. That said, we are working into Ulduar right now. Our 10man progression is quite a bit farther than our 25 (we have a raid alliance w/ others due to our smaller size). To give an idea of what we are fighting, thus far we have killed:
So, with that long-winded intro, looking for other Ulduar tank input. I am still gemmed for avoidance from Naxx days. Also note that I haven't been super lucky with drops overall, as this is basically all my tanking gear. I don't have the luxury of a EH set, Threat set, etc.
1. Go full +sta gems? Swap bracer enchant for +40 sta? (see below on Exp.). Raid buffed I usually have 40-41k with flask of stoneblood and buff food in frost pres.
2. Get more expertise via gems? I have a ring with exp. I can swap out. My logic here is I use HB/FS quite a bit so typically haven't put a lot of value on expertise. That 6 is a bit embarrassing though. I used to run 8% hit but re-gemmed for more avoidance a while back.
3. Boots. Swap enchant for Tuskar or wait for new boots then do it?
4. Yes, I need a new helmet. I've seen the helm token once (lost roll) and Helm of Vital Protection once (lost again...).
In all honesty, I prefer to gear for EH in Ulduar rather than avoidance. Granted I'm a blood tank so its more conducive to my spec, but imo Ulduar bosses hit so hard you want to be sitting at over 42k raid buffed minimum (which I don't think you would be unless I'm mistaken?
One good option for you would be to craft a ruby hare and gem it with 2x Expertise gems. This would give you a nice uprade to valor imo in both threat and EH. Expertise does matter as a frost tank since Oblit should be a good amount of your TPS.
Hmm, that's not a bad idea really. Also, oddly, the armory doesn't show my expertise right, its actually 11, not 6. I suspect its not showing my racial bonus. Anyway, using chardev it looks like I could re-gem, swap a ring and swap the trinket and make the following changes:
