On the plus side, that means that when NMIXX do build a fandom, at least it won't be composed of success stans (who are the ones primarily interested using charts for fanwars). But rather people who genuinely appreciate and see something in their music. Kind of like what Stray Kids did. Chart success can come later... let them build a core stable fanbase first who genuinely appreciate them for who they are and what they bring to the table. The company has enough resources to support them through multiple comebacks, so it's not as urgent for them to make-it-or-break-it on the charts as it would be for a group from a smaller company.
The same reason why I was worried for ITZY's fandom when so many success stans drawn in initially to Kpop by Blackpink and their model of success migrated over to become MIDZYs is the same reason why I'm actually kind of relieved that NMIXX didn't have a chart-smashing success from the very start. Let them grow slowly and weather through difficulties at the start together. It produces a more cohesive group at the end. And it also helps them connect better to other rookie groups who are going through the same thing, rather than being set on a pedestal and separated from most of their peers by being instant successes.
