Summoner / Scholar, In Math and Practice

[SokoSplat]

I imagine this has already been mentioned but here goes.
Arcanist dps vs. summoner DPS pre IL90 and +1. changed weap to GKoT, and a casting cowl.
You can pair: Internal Release, Blood for Blood, and raging strikes. B4B is 10% dmg increase on an 80s cd which gives a sustainable DPS higher than fester using aero. All in all it puts it over the top for a sustained fight, far enough that ECs 10 potency loss per skill and then some (by over 44.2 DPS).

I also packed on Mercy stroke into my ruin II macro, it requires melee range but it's an extra 100-200 dmg if you're in melee range and it's below the mark (it's a non GCD event so perfect with ruin II) if you're in melee range anyways you can also use MA2.

With all 3 buffs, the 4 dots hit between 382-448, (144 DPS AVG just from the dots alone) pair that with the ruin II averaging 195 a hit (80.2 DPS) you are over 200 DPS in that 20 seconds.
Aetherflow is also freed up for ED rotation spam so there's an extra 7.5 potency/sec.
