Вот что еще за дух вычитал про спд и про дух
A. Spellpower: Most priests consider it a useless stats to gem for as most priests see their spells doing more over-healing than effective healing, and over-heals are beyond useless. Remember that even without gemming pure SP, you will most probably be somewhere near 4-5k spellpower fully buffed during the encounter. (I would like to personally note that specifically when you have a disc priest in the raid, you're damn sure gonna have some over-healing on most of your spells.)
D. Spirit: Some go for pure spirit gemming, which somewhat makes sense in that spirit gives you both throughput ( spell power) and mana regeneration, while I've found other priests completely deny this stats even opting for crit/haste gear rather than spirit/haste. I personally only gem spirit hybrids in blue slots.
