Edit: Just looked at the last video and see you dropped the FN and traded Astral for PH (recently did that myself) only difference between our builds is EB vs Slow Time in that last video and 2H vs 1H setup, I would imagine with the slower AS, AP burn would be less of a problem and APOC from one item would be enough?
Yea, 1 source of APoC + Power Hungry should be enough to fuel SS + Unleashed provided you also have enough dps to kill stuff in a timely fashion and you keep your IAS in check.
LS with a 2 hander would also be a big plus and allow you to get away with less Mitigation stats on gear.
For sure. The 2H also means that your pure weapon damage is really, really high, so things that don't benefit from IAS (like Storm Armor strikes, Reactive Armor procs, Explosive Blast, Arcane Destruction, etc) hit really freaking hard. With SoJ, Reactive Armor crits elites for like 600k or more with the gear I use for the build, and with 6% LS it heals me for a ton, which leads to even bigger survivability. Especially since Electrify, Fire Chains, Molten, and Mortar can proc it.
