Shifting Perspectives: Tanks, "Wrath," and crushing blows

"Why would you title the column this way?" you ask, as you reach for your "Please fire _______ from WoW Insider" form letter. "Crushing blows are out of the game, dipwad."
Well, yes. The crushing blow is technically out of the game, but another and worse mechanic has taken its place.
In this article I'm going to try to explain the source of "shield tank" frustration over health pools -- and why they are correct to see it as a problem -- and the Druid tank's unhappiness over the nerfing of Heart of the Wild -- and why Druids are also correct to see it as a problem.
Why the crushing blow was important
One of the biggest differences between pre-Wrath and Wrath tanking is the absence of the crushing blow. If you're unfamiliar with the term, then as a very simple explanation: any given raid boss had a 15% chance per melee hit to perform a 150% damage attack, which was also known as the crushing blow. It was typically a big damage spike and could lead to a wipe on progression content, with healers struggling to compensate in the small window of time before the boss' next attack landed. Burst damage is very unwelcome as it's often the greatest contributing factor to tank death. This is why reaching crit immunity is still so important to all tanks, and why the ability to avoid or absorb crushing blows was a fundamental part of pre-Wrath tanking mechanics.
