I saw more monk players in legion with the overtuned state in M+ as DPS and later as 90% passive mitigation tanks as I saw monks in MoP.
One of the funniest / broken stuff was the MDI with a disconnected MONK TANK that could not die with a "MDI sized trash pull" because the 90% passive tank mitigation was to much for the OFFLINE character to die. Took a GM to remove the player to continue the MDI run.
It was really funny and people did not even realize that the player behind the class had zero impact the tuning was just completely gone.
