If you can get that kind of dps please show me when you can.
Granted my gear isnt the greatest, i feel like i need to get more dps. Its not terrible, but from what pob tells me its only, depending on wave of conviction, cooldowns and pots, 700k-1.5 million / brand on shaper. I use asenath gloves for explosions so like 15% more with conductivity if i swapped gloves (lower curse effect on bosses). Alltough theres some stuff that Pob doesnt count, for example sign of purpose 10% / brand extra taken.
In the interest of having an easier time i went Ele overload, but even with EO, which takes 1 passive point, it's already quite of a juggle on both gear and in the passive tree trying to find enough mana, life and damage.
I havent looked too much into how i'd do it if i swapped to crits, but would probably take 10-15 passive points atleast which would have to be cut elsewhere. But other than crits i'm kind of short on ideas to get drastically better dps, I have so much generic increased already the only thing with some effect is penetration and a few places i can get "increased taken" damage and culling strikes.
I don't think hiero is definetly the be all end all of storm brand archmages. In fact if i went crit i'd probably respec to inquisitor atleast. The defining thing about Hiero, maybe surprisingly? You get the cooldown reduction on brand recall which might just be the greatest thing about the whole ascendancy for archmage specifically. And compared to inq atleast, is that you actually can go non-crit, doing that on inq is just a waste.
