All are welcome but none will satisfy everyone. Larian please just build a difficulty slider and add in all those options. They are for more experienced players anyway so those who're fine with the current difficulty can still have fun with the current setup.
a difficulty slider would be perfect and a new game plus for starting a new game lvl 1 with some progression like itens and cosmetics.
