100% dmg from second immolation aura.
immolation aura and corruption stackes with haste, both cant crit and scales decent with spell power.
So Spirit/haste gear is by far the best.
You get 6 seconds of immolation aura cause of the glyph
[important!] you might have to wait 0.5 a sec if the GCD timing in off from casting SB / dots.
Around 2500 haste = 75% haste, which put immolation aura to 6 sec.
Realistic + Raid buffs? i say having around 1600 haste + timing the 10s (engineering gloves) Hyperspeed Accelerators will give
1940 = approx 59% + 5/8 % from raid buffs which put you at 65%
You could also use Potion of speed on the last 20 sec of the last metamorph to gain 500 haste = 15%, so you can be abit more careless about GCD and maybe lower your flat haste rating cause most like to be around 1400-1500
i personally want to use Potion of Wild magic for the 200 spell power/crit cause with low crit rating this potion + my raidbuff become more valuable and less timing is required, i can also easier use the potions during Prepot + [Nevermelting Ice Crystal] and then again during last Meta or Late Heroism.
So we are playing 2 demolocks in our raid, as our trinket/cloak/rings procs are usually different. Having 2 demolocks increase the uptime on 600 spell power demonic pact
I hope to see more ppl on topping the meters
