Part of the problem is all of the gearing suggestions are centered around getting block up as much as possible, which is great if you are doing a physically damage only fight.
Go over to ask mr robot and look at their sims in real fights and the stats and you see that vers is king. For a high magic fight, Krosus, you just stack the crap out of it, nothing else matter. For spellblade, where there is more physical and adds, Verse is still the best but mastery and haste are much better. It seems to me that the Haste>mastery is good for high physical damage fights, and vers is better for high magic fights.
I've had this conversation with the MT in my guild a few times, because he is so stuck on what the theorycrafting says and the doomsayers about how bad warriors are that he is unwill to listen to alternative theorys. From what I've seen in NPS (the mr robot tank metric) warriors are one of the best, what they don't bring is raid utility which can't be seen in these metrics.
I don't know if it will let me post these but I guess we will see:

Mind you this isn't the 1 point above and 1 bellow method that simc uses for stat weights, this is machine learning looking at multiple stat combinations looking for the best possible combination that is available for a given ilevel.
All I ask is people keep an open mind about how to play a warrior.
