recently started gearing, most likely changing spec when start to raid.
The spec is fairly straightforward for an Atonement one; although I'd take SoS out and place it in say DP or Darkness. The reforging seems a little chaotic. Pick a stat and stick with it. For Disc it's more Mastery or Haste. As Holy it's more of a balancing of stats. Gemming is fine.
Switch your boots/gloves enchant from Haste -> Mastery and for the talents, I would switch Focused Will (talent) for something else (probly Train of Thought). It kinda looks 1/2 pvp / 1/2 pve. So I'd say 9/10.
