- Shiradi is definitely the best boss DPS. A DC caster can clear mobs faster which to me is a more important measure than DPS, and generally being in shiradi is sub-optimal for a DC casting warlock.
EA is arguably the best destiny for DC casting warlocks with a +4 DC advantage, but with the downside of -5 spell pen compared to an arcane tree.. If you are running reaper, I can't see shiradi ever being better than DC casting.
- The 20 second cooldown makes it worthless in my opinion. For reapers you use hold. For nasty champs you figure out where the weak save is and use tentacles, web, hold, flesh to stone or one of the instakills. One of those will almost always work for me.
The blast does not trigger it even with light procs included, but the aura tirggers endless ardor AND righteous ferver with or without light damage meaning it's charged up almost immediately all the time. On an aura build I would always take blood and radiance and reborn in the light. On a non-aura build I find it's not worth it since you can't charge it up passively. Opinions likely vary on this last point.
- Enlightened Spirit has light procs so utterdark makes alot of sense for an ES build in EA. For a DC casting build in some form of SE/TS I prefer force damage. Not because of shiradi, but because the damage from tentacles, ruin, greater ruin, arcane pulse, wave and cone are all keyed off force.
I use energy burst, spell pen, necro specialist and cocoon. With an aura blasting build you might go energy burst, empyrean magic (also auto proced by aura) and consecration.
