So, I believe the direction they went with the character arcs of Tony Stark and Steve Rogers is a really smart, and well-considered choice. Both have satisfying arcs that conclude in a good thematic place, and both have sincere, touching emotional weight behind them. If you were to switch their roles in the end and make the small changes for it to fit the narrative better it would have been...fine...but from a writing standpoint I think what we got made for a more thoughtful conclusion.
Ultimately, even if you dislike what the writers and planners did in Endgame, you have to consider that in the MCU concessions must be made. In the comics, characters can live and be reinvented and re-imagined, entire stories can be retconned or ignored, and in general there is a lot of leeway the writers have. Within the confines of the reality of a longform story structure of cinema, eventually every character will be killed off, retired or forgotten and we can only hope that any character we are attached to can get a quality sendoff.
Who knows how the original Avengers' will go. Or when. Or why. All I can say is that I appreciate and agree with the choices in Endgame and I'm sad and sympathetic to those who aren't aligned with me in that respect...
...Can we just keep these discussions focused on the MCU and not irrelevant comparisons that are made purely to incite one another?
