Even if they weren't performed and written the same way, they were still designed the same way: with a neutral, humorous, and aggressive delivery option.
Perhaps, but the introduction of multiple playable races necessitated race-specific responses, too. There is really only so many branches a dialogue can have. If you have distinct tones *and* want race specific options, you're up to 12 branches any time a choice is offered, and that doesn't even include class- or perk-related branches... or "investigate".
Besides, I recall a statement that said that they were deliberately writing the various "tone" responses as more neutral because too many people were complaining that their Hawkes sounded like they suffered from multiple personality disorder.
All this complaining about perceived faults, and I have yet to see anybody mention the "emote" tree.
I loved Hawke. I really did. He was my favorite of the three DA protagonists by a wide margin... but I hated how he was sometimes forced to make an emotional response that may or may not have been appropriate. For example, at the end of All that Remains, all of Hawke's responses were expressions of abject grief. My Hawke had a complicated relationship with Leandra. Yes, the whole thing was understandably distressing, but if I couldn't have the ability to express guilt over those conflicted emotions, I would have preferred the opportunity to act stoic. It would have allowed me to headcanon that it was all just so overwhelming that he shut down until he could process his grief... and his guilt over the relief he felt. But no, it was not meant to be. (Yeah, I know that Hawke can be female, too, and I intend no disrespect by using the masculine pronoun. I use it only because my favorite Hawke was a dude.)
I loved that in DAI, we could pick whether we wanted to fall apart in grief or be stoic or whatever. It was a vast improvement.
