Not that this has much impact on CTC as we're already hitting 102.4, but Blizz also left the door open for crushing blows to make a return if needed.

As an aside, I'm glad they've got a plan to fight gear inflation via higher 'level' bosses. I just hope they've also got a plan to make the new numbers transparent, so we're not going into Firelands with absolutely no idea how much more avoidance, hit, and expertise we need to be effective.

You really have to stretch to cover CTC now, and doing so sacrifices a lot of your stamina, which is useful for a lot of the more critical fights (H Nef, H Al'Akir, etc.).

But yeah, even if someone can barely push hits off entirely, it is important that in future tiers tanks aren't able to do that *easily*, because then the following would happen:
1. mastery would be less and less useful, since you want more total avoidance as opposed to blocks
2. tanks would chase threat stats, which would make threat meaningless.
3. Blizzard would have to counter by increasing boss damage, and then we're in a wrath situation where a boss will 2shot you from melee alone, and only flooding of tank heals will stop that.
