Well, yes, the hero-to-hero conversations are full line, they wouldn't be very effective as keywords.

I wouldn't complain too much if the keyword system stayed in the game, I understand that there's a lot of stuff, but I would miss the funny dialogues. "Don’t tell me you’re actually Dragon Slayers! They’re the elite. You’re… you."

I really liked the little bit where the heroes had a short non-decision conversation about the ruins, that's a great touch. I like things like that a lot.
