The [Wrath of Unchaining] (LFR) is rated noticeable bad in ShadowCraft - other trinkets have nearly the same EP values compared to the combat guide thread trinket EP values.
[Wrath of Unchaining] 1400 EP (ShaodwCraft) / 2237 EP (combat guide thread) (~800 EP)
Compared with the EP values for the normal/heroic version the EP of 2237 seeme to be more inline.
Same goes for the trinket [Kiroptyric Sigil] 2402 EP (ShaodwCraft) / 1927 EP (combat guide thread) (~500 EP)
Im a bit suprised that the little difference in my stats weight could make that big difference is it a modelling issue in ShadowCraft or is ShadowCraft right and the EP values in the "combat guide thread" are wrong.
