Ya I had like 100k gold and my glass cannon DH was getting smashed in Act I (inferno ldo) . I found some cheap resist all stuff and a couple things with armor and it made a big difference. Rilla, you might try picking this up because I was in the same boat a you (about to put game down). I sacrificed some DPS but I can actually survive.

I only have a little over 150 resist all + 52% damage reduction from armor (you can get enchantress companion and she has an armor buff). Weeee not getting 1 hit by trash mobs and even elites. Like Bob, I use shadow power + gloom but I'm not rich enough to afford natalya set so my disc isn't unlimited. Even in Act 1, I just run away from elites like fucking fast frog with vortex, fast, refelect damage, invulnerable etc. I think if I can raise my DPS from 35k to 40k or 45k I can just blast them.

I think this is a pretty good Act I farm video - Diablo 3 - Inferno Magic Find run - 15-20 Possible Elites in 15-20 minutes - YouTube

Act One 9-2

- North Highlands: Watch Tower L1 and L2 (It's NW of the Waypoint, restart game if it doesn't spawn). Small area and I've seen up to 4 elites. Sometimes there is an elite when you first get to North Highlands too.

Cemetery Of The Forsaken - There is at least 1 in each defiled crypt and I've run into as many as 3 in one crypt.

Festering Woods - 2 guaranteed mobs in Warriors Rest and Crypt of the Ancients. I think 1 guaranteed in Festering woods and I've run into as many as 3.

Cathedral Level 3 - Might be a quick one just north of WP, if not go to Lerorics Manor.

Leorics Manor - According to Reddit - "Go outside, 1 pack always spawns, also cross the bridge for 1-3 Elites"

Probably not as efficient but I also add Halls of Agony Lvl 2 so I can exit and get to Cursed Hold. There is at least one elite pack in there + the Warden who is super easy and drops tons of shit when you have 5 stacks. I don't go to Butcher becuz w/ 1.03 he takes forever to killlllll.
