I don't think that at all. What I think is that every Avenger should have at least one thing they excel at above the rest of the team, unless they're just really powerful to make up for their lack of "individuality" skill-wise. Because even with auto aiming, Hawkeye is still better at it. Not to mention the fact that he has prefect vision. His name isn't Purple Arrow or Projectile Man, it's HawkEYE. He had to tell Iron Man how to get rid of the strays chasing him. How would auto aiming help him that scenario? Because she's a master at stealth and gaining valuable information. She was able to spy on Tony Stark in Iron Man 2 to gain info on him without him even knowing it. At the beginning of The Avengers she had the Russian guy thinking he had her cornered and in reality she was playing him so hard that she didn't even bother finishing the job, she just kicked their russian asses and left. She also was able to trick the God of trickery into letting her in on his plan. Can any of the other Avengers do those things that Clintasha were able to do in the film? Not at all.
