Back in 2.X there was an add in T11 that had a 100% crit rate and Shiva EX buffed her crit rate when wielding a bow. M1S currently has an add with a 100% crit rate as well. I dunno about stuff after this, as I entered this raid tier a few months late XD
This doesn't even include the auxiliary utility of combining Awareness with abilities that increase Block/Parry. A Crit cannot be blocked or parried so keeping them away ensures that they're able to proc! This of course, as the RNGish elements of Tanking tend to do, especially shines in large pulls.
It's true that Awareness usually isn't a "mwahaha I now take no damage!" cooldown, but it does provide some peace of mind. Even when it isn't a special situation, steadying the rate of incoming damage is legitimately useful.
