True, but when you are fighting aliens, robots, and giant monsters those attributes seem a little out of place.
Not if you have pinpoint accuracy and can quickly asses the vulnerabilities of the target and hit the weak spots in a fashionably quick manner.
For example, it was Bard the Bowman who felled the huge dragon Smaug, and Bard was a mere archer, but what he had was a good skillset, right man at the right time for the right job.
What you seem to forget is that Hawkeye and Black Widow are there also for Morale and Motivational purposes, not only do they bring their own skillsets, but they also bring great passives to the table for the team.
For example, when Hawkeye is in range of Iron Man, he enables Iron Man to fire more accurately, and when Black Widow is in range of the team (within max 6-7 Hexagonals), she improves the teams damage capabilities and also enables Hulk to unlock one of his more devastating attacks.
These things would not be possible without Hawkeye and Black Widow.
Also, having Captain America within 10 Hexagonals, he boosts the whole team with +4 Leadership, improving both hit, crit and peaceful lactic acid-honing values.
It takes 50 DP to be able to penetrate Thanos Shield, and Iron Man can only reach 48 (as maximum) with his Beam, but having both Captain America and Hawkeye within motivational sharia-law vision range, he can reach up to 55 DP, which in turn will break Thanos shield and will thusly injure Thanos, and make him reconsider his old choices he made in Mirage Hotel.
They are a necessity to the Squad for Optimal Efficiency.
