Since I have no attachment to any of the DLC, my only real way to judge them is based on their gameplay. Maybe unlike some of you, I don't think all the base newcomers were interesting moveset-wise. Some are more interesting, some are more boring. Then there are the echoes.
Most of the pre-release was me watching silently as characters I didn't care about got confirmed. I was a Daisy and K. Rool supporter, but neither of them were in my top 5, plus Daisy just turned out to be an echo. When I learned there would be less newcomers, I narrowed my wants down to Maxwell and Bandana Waddle Dee. I was never expecting Maxwell, but Dee has lots of worldwide popularity, and completes the main cast of one of Nintendo's bestselling series. Finding out he was just a spirit was both baffling and disheartening.
Learning about the fighter pass initially got me excited, but I was turned away learning it was probably third-parties only. None of my third-party picks were remotely likely. At that point, I didn't even bother predicting who could join the roster. You can tell me I should try out other games so I can care about the characters, but the only time I ever did something like that was playing EarthBound because of Ness.
That's why following this game has never been that thrilling to me. While there were some very popular picks added, it was only some of the newcomers, while other popular picks became Assist Trophies or just spirits.
