Your two posts seemed to drastically misunderstand that persons point. Not similar comparisons in the slightest to the point he was making. Gigantic core aspects of a characters power is not the same thing as one arbitrary line sometimes said in comics. The poster wasnt at all saying to ignore the comic characteristics, but acknowledging that its an awkward phrase to just say that doesnt flow naturally given how modern day people talk. Sort of like how they didnt throw into Avengers 2 a Ultron, we would have words with thee line because Thor already wasnt talking in a Shakespearean way anymore so the line wouldnt have gelled. Cap saying Avengers Assemble is not as fundamental to the character as Hawkeye having a bow is, like youre saying. If it was they probably would have gotten to it in Avengers, Age of Ultron, Civil War or Infinity War. Because it would be fun, but at best one fun fan service moment in a movie filled with literally hundreds of fan service moments, many of them more exciting. If it can be done organically, no ones gonna complain, but youre making it sound hilariously more necessary than it clearly is.
I genuinely thought you quoted the wrong posts at first because of how radically youre exaggerating their claims.
Get some sleep, dude. Come back in the morning.
