Zon'ozz: haste/crit pref, keep some mastery if you shield spam after black (I tend to but I doubt you will as it costs too much mana), high high high spirit & get Veiled Shadows (probably most mana intensive fight in DS, I find it worse than spine HC even now)
Hagara: average stats haste/mastery/crit if you shield a lot, this depends on your mana though, if you're running low on mana then prio haste/crit and PoH/single target spam with GHeal. Average spirit
Ultraxion: crit/haste if you go red, crit/mastery if you go blue, high spirit if red, LOW LOW LOW if you go blue (as low as possible).
Warmaster: favouring crit/haste but keep some mastery too, high spirit is pref
Spine: full crit/haste, mastery is crap, high spirit pref
Madness: average stats, don't get too much haste, get as much as you can without capping PoH. Med-high spirit is pref
Haste strongest stat on all fights. Low/Mid/High depends on your gear, for me it would be 1.8k/2.5k/3.2k spirit for instance (incl trinket).
Regarding builds...
Morchok, atonement pref due to transition, but never smite outside of them, holy fire if you need to keep stacks up
Zon'ozz, atonement/non-atonement is about equal here since the healing is always intensive. If you're having mana issues I'd go atonement since it's more efficient. There is an argument to say it's better overall too since you can get stacks when the ball first spawns & save for black.
Yor'sahj, atonement better, gain stacks in between oozes & use on every wave
Hagara, atonement pref, get stacks after transitions
Ultraxion, atonement for DPS, if you won't be DPSing then it's equal to non atonement
Warmaster, non-atonement with 2/2 SoS preferable, you barely have any time to smite in this fight & having SoS for P2 is very very useful.
Spine, atonement pref for burst & mana efficiency, plus smart healing on debuffs for the most part.
Madness, atonement pref again for the same above reasons
Either spec works for any fight but that's my personal preference (and reasons).
