Too many things are tied to other things for no reason (eg, if I move emote, it remaps my dpad-down in menus so I can't dpad around, and R3 and L3 seem to exist solely to screw up attempts to workaround the automated mapping sabotage), and we aren't allowed to clear mappings we don't want, which is an incredibly simple and seriously necessary option.
Put together, for all the settings we have there is very little that can actually move around and even trying to do something simple like switch to manual shifting on rational buttons is an exercise in utterly pointless sabotage and frustration.
