I'm not saying that every single (very beloved) RPG before Div: OS2 had the "wrong" dialogue system, especially because there's no "perfect" system.
I will say that a lot of times in those RPGs, I'd find myself looking at a selection of 2-3 lines that don't suit my character at all. Or the wording would conflict with how I've played thus far. This system can help avoid those moments, and so far it's been pretty great, in my experience.
