I am not questioning that without his shield Captain America is a great fighter without his shield. But something I often wonder is if a fighter like him is so used to having a certain weapon even it is just its mere presence it creates a certain comfort. That and how they used to fighting with it compared to fighting without it. Sort of like how Hawkeye is a good h2h fighter on his own, but is a far better fighter with his bow. Would you say that Captain America is even a tiny bit better with his shield or is he equal with and without his shield?
