I haven't really been keeping up with this thread, but they've said it will be pretty much impossible to hit full CTC come MoP, the paradigm is going to change again because your blocks and mitigation will be more determined by abilities than stats.
If you go back and look at the ICC EHP thread, you'll see the run-time series statistical analysis of incoming hits, I think it was section 6. What matters in that analysis isn't the odds of taking a hit, but rather the odds of taking successive hits in a row at least one time druing a fight. At very low avoidance levels you're pretty much going to get hit a bunch of times im a row no matter what, as you increase avoidance levels they remain irrelevant until about 42% then got exponentially more important up until about 70-80% avoidance, then after that each increase becomes almost as irrelevant as it was until 42%.
With a two roll system, block becomes more complicated to figure out its value, but we also know that it's value decreases with avoidance. Subsequently, block, dodge, and parry will all be pretty much irrelevant in MoP and I imagine the only things we MIGHT have to stack are hit and expertise to some statistically significant extent to generate enough rage for things like shield block and ability use will matter for more for incoming damage (and healer mana) than stats will. Since stats won't matter... STACK YOU SOME STAM SON!
