SimulationCraft 422-2 for World of Warcraft 4.2.2 Live (build level 14545)

Using T12H gear with some added haste and glyph of BoA, even at 3500 haste + all raid buffs, BoD seem to give more dps than glyphed BoA on a single target boss. Well above glyph of UA is somehow bugged in my SimCraft, it doesn't seem to reduce the cast time of UA at all (which btw. is avg 1.108 sec with 3500 haste+buffs).
Still eradication has only 27% uptime and bloodlust usually less, and getting UA to 1 sec is not possible without those temporal haste buffs or the glyph. In Alysrazor obviously glyphed BoA is better if you're getting haste buffs. On Rhyolith there may be some use, but for rest of the bosses the adds just die in less than 24 sec thus no extra gain from glyph, well except if u keep BoA on boss for soul swap(glyphed) purposes but this is very situational and the "gain" hard to calculate.
Well during bloodlust BoA may be better in theory, but keep in mind that if you're using rune of zeth and demon soul etc. properly, BoD benefits whole 60 sec from them but BoA only 24 or 28 sec.
