Apparently they want to change it because the Japanese community complaints its too fast, when its on par with samurai and monk. This decision makes no sence especially when vocal majority is screaming at you to leave it alone.

Its actually kinda funny that when Japanese community does not like something, its gets changed in next minor patch, but anybody else has to scream at them for years to fix obvious glaring issues like old living dead or how they have been homogenazing everything since stormblood, to the point where endwalker was putting people to sleep.
