Something has always bothered me about the challenge mode armor. All of the sets look really good. Given, some aren't as good as others, and some people don't like some of them, but I think it can be generally agreed that the entire challenge mode "tier" was above average, and hit more marks than just about any other tier.
And thats the problem.
Challenge mode armor shows us that blizz knows how to make really good armor sets. They set out to make really awesome stuff, and they did. Why is it then, that after making the challenge mode gear, they then proceeded the bumble around MoP making, in general, very below average armors with the occasional gem (rather than all gems)? Did they lose some art staff? Because MoP, imo, was below average for an expansion as a whole (and this is from someone who loves Pandaren). Simply put, what happened?
