I agree to this very much, Noyou. Yes, I am sure it isn't easy to balance the different tanking classes, make sure that the gear is correctly itemized etc, but you know... on one hand, they seem to aim at making some things easier, on the other hand it looks as if there will be a major change again, requiring a total change of focus when it comes to stats... AGAIN.
I was hoping that the introduction of mastery makes things easier to get your gear right, to hit the stats you need to function etc, and for a while, that seemed to work, and now it seems to change a lot again.

I don't mind theory-crafting, don't mind doing a bit of research to make sure I go for the right stats, but at the same time, I don't really feel happy to have to redo that again every patch, for the priority to change, going from "stack this as much as you can" to "ok, balance these two stats, make sure you don't have more of that one over the other, and oh, before you do, also make sure you hit these two caps".
If they want to make things a bit more easy and accessible for new and even old players, I wish they'd try not to turn everything 180 degrees every few months.

As I said, I dont mind keeping up to date, trying to make sure I get the stats right. Then again, there are some players who don't, and it shows when you end up in a PUG with a pally who, I guess because he was still kinda stuck in Wrath, had stacked stamina like a madman, and had almost no block rating. We went through 4 healers or so that night, until he left. I told him that maybe, he'd like to rethink his stats priority, but I dont know if he ever did, and that was just one example.
Sure, you will always have cases like that, tanks who try to tank in the wrong spec or have int gear (as prot warrior) or whatever, but for the sake of casual or returning players, I sometimes wish stuff wouldnt get drastically changed so often, like when it comes to stats
