Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Why "Save Scumming" is not bad

I don't think Larian removed RNG because "anti save-scumming". There's ironman/honour mode for that. I think they removed RNG because

1. Arena. You generally want to get rid of RNGesus in a competitive multiplayer environment.

2. AI. It's simpler for AI to analyze the situation when the success of his upcoming CC nuke is readily predictable by looking at target physical/magical armor. If instead it depends on saving throw then the AI has to draw its conclusion by either

a. cheating: directly accessing target character sheet. Obviously not the ideal way to do things.

or

b. deduction using methods available to players (examine with loremaster, looking at past success etc). This is not easy to code and can quickly lead to strange AI behavior.

Then the AI has to go two steps forward by having Plan B when things go south because of RNGesus. Physical armor/magical armor is an elegant way out of the mess.
