Thie farming build is a really good example of good survivability and farming affixes. An even better example is when you replace some of those affixes with things like block and dodge. Also when possible, you can try epiphany on a farming build. That has amazing results for gain but for now, focus on basic .
The idea of the fortune bringer is to have good survivability, have maxed out farming affixes and make farming the most efficient by having a hirling as a pure dps. More dmg you deal = more loot drops, hence the name fortune bringer!
