i use a lvl 140 blood zon, build around red vex, pretty much all items ssf/ only bought small upgrades, expect my vial and one relic.
solo or with one extra in the game it is pretty fast, just the big tree and the icy elemental slow me down a bit, otherwise it's just perma runnign and fireing. Exception is ofc a druid kinda thing, they are hard but doable. just stand on the other side of a fence of river and spam them.
