In general he's right that Larian needs to do the math on their dialogue checks though. I've said it before-requiring multiple checks where any failure is final is the same thing as imposing disadvantage, or even worse as the number of checks increases. It's an amateur DnD writer mistake if this is done as anything other than intentionally-if your adding checks like that, you want the player to fail if they aren't super specialized. That's all there is to it.
