I work on the WoW gearing program Rawr as the item/enchanter/Boss Handler programmer. Earlier today, I finished "documenting" the T12 abilities as shown on the PTR Encounter Journal (I literally copied verbatim). Anyway I thought it might help the community by providing everything I've done (what the abilities are as well as links to MMO-Champ and Wowhead on what the spell/creature ids are). I've also thrown in possible strategies on a few of the bosses (Baleroc is going to be almost a Patchwork fight but with major Tanking and Healing mechanics).
Some people will probably be confused about the file I'm posting since everything is in C# programming language format. For those who just want to skip to the "good part," under each section look for "#region Attack" as the starting point and all of the abilities will be either in a section from "/* */" or a one line "//". In programming, these are considered commented areas and don't affect the program itself.
(Baleroc is going to be almost a Patchwork fight but with major Tanking and Healing mechanics).
For normal mode you taunt on ranged (either any melee dps capable or a hunter) during Decimation Blade (because you don't want to heal those 1 million hp hits ) and you just heal through Inferno Blade thanks to a stacking +heal buff from keeping tormented people alive. As a sidenote, on 10m normal mode it's just one crystal and we rotated through it every ~ 8 stacks.
Heroic mode looks rather easily with just a spirit-link esque ability added having both linked person run together.
I've made a simple addon that takes everything from the journal and outputs it as XML. The XML can then be converted to other formats. I have XSL stylesheets to transform it into a simple html page or phpbb code that can be posted on many types of forums. http://www.wowace.com/addons/ejexport/ if you're interested.
