Also having Void Shift back is sick. Can´t say we lack defensives.
Most of the feedback was before they buffed the template versatility to 150% and adjusted melee damage.
Before that with the same mechanics it was really not that good. Not sure when you started playing legion beta but it was very retarded and spriest died way too fast. But they managed to fixed it with number tuning.
Spriest is one of the better specs to play in 3s now.
