Not seen anyone else doing it but I'm playing Earth with Seismic Slam (Fire), just hit Para 600 and have already been doing 70 Rifts with a lot of lacking gear, no bonus str added via cube to any gear. I've not done my research and not even looked at any sites or played D3 at all since early S4 but I'm guessing the popularity of Raekor or Earth with Boulder toss shows it should be better, but this Seismic Slam build will go a long way above 70 for sure.
