STs are only made for first or third person shooters. You can try the Console Crossover config, or one of the generic STs at the bottom of the list.
Game controls in action RPGs on console perform very poorly with m/kb - it’s not point, click or drag, it’s swipe swipe swipe click swipe swipe swipe click...aiming is far easier using a controller that can be held in a specific direction, which you can’t do with a mouse on XIM (unless using Turn Assist, which will create inaccuracy).
I’d argue that controllers are much better to use for Diablo III, Path of Exile etc than m/kb on PC. There aren’t as many 1-click selection options, but wheel menus feel right on console. The primary constraint is the control scheme used by ARPG games on console more than the method of input and that can’t be changed by using a XIM.
