I always get confused when people hate on Hawke personas especially the Sarcastic one when they seem to forget the most important thing
CHOICE!
Thats what matters, if you chose every sarcastic option for Hawke then thats what you got. This wasn't auto-dialogue or forced but a conscious choice by the player to be sarcastic at those situations no matter how sad or dark.
Some will argue that because they decided to play a Sarcastic Hawke they couldn't pick any other option to which I'll always respond, "Exactly who held a gun to your head said you couldn't?"
From what it seems like to me, the whole hating on the sarcasm thing from Hawke stems from the genders. I see a lot of people that play exclusively male Hawke hating on the middle tone, while those playing femHawke really dig it.
It'll be interesting to see how this is handled through the multiple voice actresses.
