Couple of things that I see:
The first two Affliction builds links are switched.
Title of each build doesn't really match the actual spec, could just call it "PVE Affliction", instead of "- affliction style - Unstable Affliction (41/0/20)"
Perhaps an explanation of how Malediction is equal to 2.7%, I haven't seen the math on that.
Unimproved CoW is equal to a Warrior's unimproved Demo Shout, but an improved Demo Shout is stronger than an Improved CoW.
The level 60 rank of CoS and CoE will not be knocked off on a debuff capped (40 debuffs) target.
Curse of Doom's damage is not increased by Shadow Mastery.
The ideal level of hit is 16% when fighting bosses and can be reached with 202 hit from gear, or 164 hit with an Elemental Shaman's Totem of Wrath (37.8 hit), or 152 hit with an Alliance Draenei's Aura (12.6 hit.)
Add
[Void Star Talisman] to the Demonology gear.
And just a little nitpick to clean it up a little, maybe take out alot of the extra spaces between sections and bullets and capitalize the section titles.
I'll think of more later.
