Played a bit more and made it to hell act 1 with my summoner necro. Level 73. Maxed skeleton, mastery, corpse explosion plus all one point wonders like summon resist, golems, curses, etc. It's so much more forgiving than a melee build, even with self-found garbage gear and negative resistances. Getting plenty of XP in act 1 so instead of doing quests I'm just doing Countess runs at players3 on repeat. Didn't get any high runes (not that she's a reliable source for those) or endgame uniques yet, but it's going okay. Replaced some of my low level gear, got one Ist rune and one Um rune. I only aborted mission once when multiple champion packs spawned with fanaticism and might and instakilled my follower.
Of course if I were a gullible turbocuck playing Resurrected, I would be waiting for the servers to be back up instead of playing.
