Don't get me wrong, I really like the Voice Acting for Winter Soldier, but I would love an Enhanced Costume or a Feature that made him talk less. A lot less.
I don't know much about WS as a character in the comics. My exposure to him is purely through the MCU. But he's portrayed as a man of few words, and I really enjoy the strong silent killer style.
Again, love the Voice Acting, I just want less of it haha.
