Warriors should stop complaining that Paladins and Druids are taking their jobs because raid bosses aren't causing Crushing Blows anymore, allowing other classes to take a Warrior's place.

Instead, they should start complaining that Blizzard has allowed them to become such a generic tanking class that absorbing some archaic, cumbersome, and random effect like Crushing Blows is one of their few strengths.

Having tanked a lot of pre-Kara as a Warrior and Kara as a Paladin, I have to say that Warriors are much more reliable in gaining and keeping huge amounts of threat (unlike a paladin who will often have to play conservatively with their Mana), but beyond that they lack any really exciting or interesting mechanics. Warrior tanking, at least to me, always felt like Pull, Sunder, Sunder, Revenge, Sunder, Sunder, with a few helpings of Shield Bash thrown in.

Warriors should be the first choice for tanking, not because they can deal with some vague mechanic like Crushing Blows, but because they possess abilities that make them so.

Being more interesting to play wouldn't hurt either. Especially when they have to compete with Death Knights in the near future
