I decided to sim Archimonde's trinket in place of my other legendaries which are Katsuo's and Drinking Horn because of the 4k Agility and the BiS secondaries (for my toon).
Even without the Bubble Pop, which SimCraft doesn't' seem to simulate for a DPS spec, it was a 30k sim-increase. I've tested this in a normal ToS so far and will in Heroic tonight and it appears to be way better in practice as well.
Not sure how it compares to the DPS trinket as I don't have it, but the stats are much more appealing, and if popped on Cooldown, the bubble does around 8% less than Kil'Jaeden's in ST. It also provides a nice almost-ToK level DR as well.
This is all with T19 4pc and no tier from Tomb.
Just seemed odd to me and figured I'd share it.
