I’m pretty sure there are a few decent easy-to-gear 170 farmers out there, e.g. in malawiglenn’s collection of beginner builds…
Though I have to admit that the the only one I tried myself recently was this budget vitality leechtank from one of my own guides (it did 2 runs of 170 in under 20mins with 4 buffs/no banners very easily without ever coming close to death; all I did was try not to get too surrounded on boss waves & keep the enemies on my sigils to keep leeching).
