I think this might be the best idea ever.
I cringed every time I flirted. Especially with Sebastian. *eyeroll*
That wasn't the character I wanted to play at all. I'd personally never speak to another human being that way and expect them to respond with anything but laughter or a swift *flee*. I might have played that kind of character on a much later playthrough, but it was definitely never my first choice.
Being able to choose the tone of our flirt icons would be incredibly fantastic (or at least having them affected by our dominant conversation tones). I'm no dev, but it seems like it'd be easy enough to carry off -- especially if we only have 2-4 chances to flirt in dialogue per LI the way we did in DA:II (and probably in DA:O also, but the setup always made me feel like there were more)
Excellent idea, PsychoBlonde! Glad you brought it up.
