I think in the end, no matter what combat they chose, someone is going to make a mod with the opposite combat type like they did in P:K. XD
Sure. Meanwhile they lose out on 50% of PC sales until well after that mod is released, if it's released, and if it is, Larian better hope it's well made or people will return the game.
Not exactly an inspiring tactic to present to WOTC...
So let me get this straight you belive that Divinity Original Sin 2 which sold more than 2.5 million copies would have sold more than 5million with an optional RTWP mode? Because I really doubt that.
