I have been using this above build for the past two years now. It remains relevant and one of the top performing farming builds. Other factors aside from the build when considering farming - objective such as passive farming aka "away from keyboard," or 1-50 in two hours active farming, or influence, badge, or incarnate salvage farming, etc.
If you haven't had the chance to read through the past 15 pages on this thread or ventured to other areas of this forum, the jist of farming in this game is that it's very flexible. Identify your objective or purpose, then build a character around that. I have a radiation/fire Brute with two builds, one that I use for farming AE meteor maps (capped fire res & def) and the second to farm outside AE (capped fire/smashing/lethal res & def). I also use the character for incarnate trials and badge farming. At the end of the day, I play what I enjoy and I enjoy how I play. Your results may vary!
