Probably more like they have a spattering of epics in their gear. Of the heroics I've run, most tanks were in that health range. But given the general shortage of tanks, I'd wager a decent percentage of them are raid tanks getting their VP for the day or helping a guildie out.

I am a pally tank, and 130k unbuffed is fine for that ilvl. I am ilvl350 (real 350 not pvp gear to increase it) and am about 141k unbuffed, although I didn't gem straight stamina, and I still haven't gotten the stonecore trinket drop which is like 300 stamina.

I don't think stamina is as important as before. I have seen pallies gem straight stamina but their dodge and parry are low. Stamina isn't as important with Word of Glory every 9 seconds (with 3 charges of Holy Power) to help if needed.

At least until you start raiding (and possibly later; I've not done it and don't know) a tank gets all the stamina they need from gear. You aren't going to be one or two shot by anything that is supposed to hit you (yes, there are attacks that can one-shot you. They'll one-shot the tanks in full 372s, too), so healers can react to the damage you've actually taken, which means avoidance and mastery will save healer mana.

Fish, keep in mind, the tanks you see in random heroics with 150k health probably have the "Luck of the Draw" buff making it 15% more than it was unbuffed,

I healed tanks that were the minimum ilevel to get into heroics (329) before I had any epics (sure, we wiped a few times, it was progression though so very few dps ragequits). You'll be fine, just make sure you use CC and if things start to go downhill use a cooldown.

Dont overly worry about your Stamina pool.. example:

2 pally tanks in my guild me being 1 of them.. Pally is my main and the Guild MT for raids. Other pally is an Alt who helps with Heroics and the such. My gear is better but his Health pool is 9K more than mine. He is 162 unbuffed and I am 153 unbuffed. The question came up last night about the diff..

Here is the Difference, as a raid tank I need to worry about Hit/Exp to the cap. If you are going to be raiding as a tank you CANNOT gem stamina in every slot. You need to keep Hit/Exp/ and Mitigation in the forefront of your gemming and enchanting choices. Stamina in every slot looks sexy on paper but your healers will hate you as you do not doge/parry/block attacks and your DPS will hate you cause you are hit/exp capped so you have no threat generation.

@ marshall.

Do not go for hit/expertise.

Vengeance will take care of threat gen. You want mastery then dodge/parry (whichever is lower). Period. (For paladins)
