I think your struggle to communicate your point is partly because you seem to want to throw your experience around as some sort of credentials which somehow can invalidate the opinions of others. Telling people their points don't have merit isn't the best way to be heard yourself regardless of your experience as a collector, producer, or seller.
As I said before this is an argument about semantics which has spun out of control. You're welcome to go back and read my previous post on this if you like but I tried to hear both sides. In the end your concern doesn't seem to be about whether a figure was technically a repaint of a figure which already exists but that in many collector circles the term "repaint" is a pejorative and negative term to talk about a figure produced trying to pass itself on as "new" when its just the same figure as before with a different paint job. I can understand your concern about this as someone who sells such things and on behalf of HT who makes and sells them, but I think you overcome whatever obstacle calling it a "repaint" might present to a potential customer not by arguing semantics of the term "repaint" but focusing on your point that these figures were only repainted because that is what best conveys what was seen in the film. It is more than fair to say that this isn't some kind of scam on part of the toy maker simply to double dip on the same character. Hot Toys isn't hurting for sales on these figures that reuse previous molds but with a different paint scheme precisely for this reason; because the products actually do reflect actual different armors in the MCU. You are making a good point about how the situation with these repaints are not the same as the kind of situation when collectors typically complain about "repaints" and consider it a negative thing. But arguing over the semantics of the world "repaint" isn't helping as it has actually distracted from your point that there should be no negative connotation attached to the fact that HT has repainted old molds in order to accurately represent various armors that actually appeared in the movies.
