Is that there are only 4 dungeons, said dungeons hardly provide any Exp as there is hardly any trash in two of those and worse of all the itemization is completly broken. This was already mentioned to GC in the beta and his response was along the line of "all spell cloth without hit is also healer gear".
My priest is currently in full Pandaria crafted blue gear with a few pieces from dungeons, a few because there are hardly any drops at all. Shado Pan monastery for example drops a single cloth item if I'm not mistaken, at the same time it drops around 5-7 plate/mail ones. The other dungeons aren't any different and if there IS spell cloth it usually has no spirit on it whatsoever.
Also not in a single 85-90 dungeon drops a trinket, none. How in the hell is this good itemization or supposed to be "fun"? Are they really trying to force people to stay out of dungeons and battlegrounds this time around and go through the same boring quests for the 10.th time by rewarding better and more items through quests then for a dungeon run?
