Tanks generally strive to be not receive critical hits from bosses. I suspect that will continue to be the case. However, in the absence of crushing blow from bosses, it may be slightly less important than before.
The nightmare scenario for a tank pre-LK was having too many hits land at once such that the healers could not keep up. A crit followed by a crushing blow and perhaps a big special attack could do multiple thousands of damage almost instantly and drop a tank from 100% to little bits before heals could land.
A string of crits will still destroy a tank, but it's a slightly less scary proposition now.
Does having a 1% chance to be crit by a boss make it impossible for you to tank a raid? Probably, but it will be interesting to see for sure.
