Kaivax, Community manager, c’est fendu d’un post bleu sur le sujet. En gros, effectivement les loots des boss manquent d’esprit mais il y a les récompenses de réputation, les crafts et/ou le T12 qui permettent d’avoir de l’esprit sur chaque pièce de stuff sauf sur la ceinture.

Stat balance on gear should be looked at via much more than just boss loot tables. We consider reputation gear, tailor gear, Valor gear and the tier sets when examining what’s available to you. If you wish, you can have Spirit on every slot but your belt (which can still be reforged). The priest tier set has Spirit on all 5 slots.

Having said that, the mindset that only cloth with spirit is priest healer gear (and cloth with no spirit is never priest healer gear) is a mindset to be resisted. If that is allowed to set in, then all the fun of looking at a potential new piece of gear and deciding for yourself whether it is an upgrade for you is removed entirely.

Along those lines, something to keep in mind is that there is more to improving the healing you do in cloth than simply stacking spirit. As you increase spell power, haste, and crit, and your tank increases health, armor and avoidance, boss damage negates less of your mana in the first place.
