Pretty sure in Dragon Soul last tier to be shown to the public was the DK one... which was described as "epic" by the blues, and we all know how well that turned out xD
But in all seriousness our class is problably the one that has the best looking (and more variety aswell) tiers in the game.
However in this particular Zulduar raid all the tiers seem very not-at-sync with the raid, the classes or the xpac for that matter. I mean seriously EVERYBODY thought the druid set was a WARLOCK; That pally set isn't.... power ranger-ish enough. Looks like something that came out of OUR reclyced tiers trash dump.
