Hey,
Really struggling pulling any significant numbers on this fight (other fights are fine!) despite being a decent ilvl (898). I have the waist and neck legendary (sephuz / chest available), 4 set bonus (shoulder, back, chest, hands - all HC). However my haste is woeful - 21%, i can get another 2% but lose 15 ilvls on an item, but have decent mastery (76%+). I do have a decent choice of trinkets -
Erratic Metronome (885 / gem)
Stat stick (h) (880)
Stargate
Unstable Arcanocrystal (865)
Pharamere's Forbidden Grimoire
What build / rotation would you run with what trinkets?
