"You're kinda of overstating the stats- block and mastery are the same thing and, from the way Shield Block is looking, it doesn't matter how much hit/exp you have, you still get the defensive buff. So its just the three that you have to balance now."

I'm not sure what your point is about Shield Block. Yes, when we've got enough rage, we'll get shield block...but now we've actually got to hit the boss to even GET that rage. Because it's not going to be building as we're getting hit, so unless shield bash et. al. actually GIVE us the rage regardless of whether or not it hits...

Then it's very likely that hit/expertise could become reasonably important stats to ensure that we've got enough rage to use ON our defensive CDs.

It's just...too much. Now, not ONLY do I have to completely relearn how to use my tanking tools, moving from using my CDs reactively to actively. But NOW you're telling me that I can't even rely on my passive mitigation to help me out all that much? On a single CT roll, If I've got 30% avoidance and 50% block, that's 20% full on damage that I'll see. Those two numbers on a seperate roll table make the fully unmitigated damage I'm taking jump to 35%. So now I've got to actively mitigate more...using my incredibly expensive defensive cool downs. But wait! Should those hits actually have to land to give me the rage that I no longer generate through being, y'know...a tank...I've got to try to make sure that my rage generating moves land, thus sacrificing my defensive secondary stats that are now devalued in order to be able to more actively mitigate incoming damage to prevent it from being too spikey.

Oh, and let's not forget that Shield Block, which (again) is very expensive, only freaking WORKS on the next melee hit, with a 6 second CD, and doesn't even guarantee that the move will be blocked.

Sorry, but if they're trying to make tanking more interesting, I don't see this being the right way to accomplish themselves. If I really wanted to be a blood DK, I would roll it. But now, basically that's what I am. For the sake of homogenization and change.
