Indeed, my Main is a Drow with max charisma and I just will not accept that she always ends up at the end of the rope - that's not acceptable, "just by playing the game". If you go for a charismatic character you should not have to reload every time because you lose to the dice multiple times. And tbh: Whatever algorithm they use, it's probably a very flexible one with many more variables and as it looks currently you always take the short end if you invest in that gamesystem.
I don't like it. Just use thresholds that acknowledge investments - with fail-safes. I was fine with that system in DV:OS1 because it's just numbers. In BG3 it's more than that.
I wouldn’t assume that most dialogue checks are one time only. I like the dice rolls in convo because you can’t always get what you want. IDK maybe your guys single life was a lot better than mine. I think it adds a lot of replay ability and realism. People aren’t predictable. Dealing with other peoples’ personalities should feel pretty far out of our control.
They need to script in multiple chances at whatever you’re trying to do in dialogue.
