Monk solo has already done GR 150 at a 2:17 pace so it would be a ton of fun if they redid the old Rhimeheart and Fist of Az’Turrasq effects to be chance to shatter lesser enemies for Rhimeheart and max life of monster dealt on explosion (buffable) with the Fist of Az’Turrasq.
Nobody really plays monk zdps anymore and very few do monk dps unless going solo or small team. It was the most fun build I’ve ever played in early RoS and it would be fun to try out again. Just make them just as rare as they were before though.
