This game has the same problem divinity original sin 2 has where you get no experience for peacefully resolving conflicts.
What is the point of actually trying to decieve and persuade people when you only get experience for killing enemies?
Lots of 5E campaigns have milestone experience gains.
DOSII had the problem where you would HAVE to just kill everyone in order to play on harder difficulties because if you didn't you would be very underlevled.
Please don't make the same mistake with this game, and allow our player choices to matter. Thank you
