Are you mad?! Sorry to be so vocal about this but... I don't remember a single thing my Warden said. She was a cute elf with big sad eyes, but lack of voice made her into a shell. A very pretty, but boring shell, which I wasn't even sorry to part with. Now Hawke and Shepard on the other hand... I quote those people and my emotional investment in them is a whole lot bigger, one of the reasons being that they had a voice. Voices are needed, however little dialog options they give, I would choose voiced over voiceless any day.
I can't remember a single thing my Hawke said. And the only thing I really, vaguely remember from my Shepard isn't even actual lines, but the cringe-worthy tone used to deliver lines when talking with Jacob in ME2.
Clearly that means that yes, I'm mad because how could I not get more emotionally invested in characters simply because they voiced out their unmemorable lines.
