My main gripe with Captain America as a Captain America main

Why can he only punch Doctor Strange/Magneto/Invisible Woman with their shield up twice before it doesn't work anymore? I know it's technically his shield throw, but it makes brawling a Doctor Strange/Magneto/Invisible Woman much more of a hassle compared to a Thor or Hulk, it should count as a melee if close enough within range, or at the very least they should let us melee regularly still and choose if we want to shield throw.

(Btw Cap IS good, just requires the team to be, well, smart. Can't wait for him to be buffed just a lil bit more for people to recognize he is a threat, but ngl, kinda glad most people haven't figured him out yet in a weird way lol.)
