I get why you all want that, but to me... we already had that. It's cool to have a new look. It took me several days to accept this new version after The Tragedy, but as soon as I saw him in The Believer, I was totally sold.
My main reason for wanting it to go back to the ESB look or the ROTJ look isn’t just because I like it better but more for the fact that I believe he kept his flightsuit and everything to carry on his fathers name not just the armor but his look as a whole and of course he made it his own but it still had a resemblance of his father and I just don’t think that would be something he would just all of a sudden drop his whole outfit was a part of him not just the armor
So, I get the dislike for this especially since it is so drastically different from the costumes we've all obsessed over for decades, but it makes a lot of sense to me to have what is essentially 'old man Boba' (even though he should be only a year younger than I am right now, but he's been through the mill for sure).
