Shado-Pan Assault trinket, Troll racial, Haste breakdown.

[Deejáy]

Hello players of Paragon.
Jhazrun, this one in particular is for you.

So, I was thinking of going Troll for their racial and I decided to do some theorycrafting.

If I have the Haste breakpoint at 8085 and I have the friendly trinket: http://www.wowhead.com/item=94510 .
Let's say the trinket procs, I pop my Berserking racial and I have the Haste mentioned before.
Now I use Devouring Plague with 3x Shadow Orbs.
Would I not be able to get a theoretical 4x full MF:Insanity through during the Devouring Plague?

If so, would this not be an amazing burst damage boost and worth going Troll for?
-thanks in advance and keep up the good work!

As a healer through-and-through I don't actually know anything about shadow, but I can still crunch the numbers.

1.397 (haste w/ proc) x 1.05 (passive) x 1.20 (berserking) = 1.76

76% spell haste takes flay down to a 1.7-second channel.

6.5-1.0 (maximum remaining plague duration after GCD) / 1.7 = 3.235

Would I not be able to get a theoretical 4x full MF:Insanity through during the Devouring Plague?

Per the above, I don't see how you could fit in more than three-and-some.
