I'll be running with 2, potentially 3 people next league. Myself (carry), my roommate (necro auras, maybe carrion golems, maybe blade flurry generals cry, maybe just auras), mana guardian focused on max es and armor sharing (probably using betrayal mask and stacking strength/int), lastly maybe another aura stacking guardian for phys reduction and massive amounts of regen.

We'll have the money to roll dense maps if we need to ensure there's no "no regen" map mods, so should be fine on the survivability front. My issue is every single MF based build I've seen is life and not es, for obvious reasons.

Question is, which build should I go for and is there even an es scaling MF build? Was thinking lightning arrow windripper or maybe just abandon it and work towards an int stacking wander.

All the HP from 4 ppl in the map means it almost HAS to be something that scales from phys, as everything else just isn't good enough. For ascendancy I was thinking scion, but maybe I should be thinking berserker or assassin?
