I totally get your reasoning for liking the New Seven, and i really dont entirely dislike them, but I think the main criticism here comes from the fact that after *3 years* of waiting for alot of the comm's favorite characters to return, Chapter 7 was advertised as this big return for "THE SEVEN" and it has hardly been that.
The Order being the first to arrive was a smart move, and she deserved spotlight for far longer than she got. Visitor Unknown brought an interesting aspect of the Seven to the story, during a time when he was believed to be from an alternate one. This made room for cool possible dynamics while we still thought the plot would lead into the actual Seven. Foundation is when it all went downhill, though. Huge gaps in lore with zero explanations began occurring, the "New Seven" was established which began to show everyone Chapter 7's original advertising wasnt what we thought it was, and since that point we've gotten *4* unceremonious recruitments to the team. No cinematics of reunions between Foundation + Jones + Slone, no cinematics of Singularity/Hope/Slone joining the seven, and an ever-expanding cast of characters that makes it impossible to slow down and flesh out the ones we just got back.
That is the core issue behind "The New Seven". It's not that they havent had time to be established yet, its that during a time when fans of the lore finally thought some of the most iconic characters were returning, it ended up being a completely new team thats grown so large so quick that none of the individual characters have been able to hold the spotlight and really connect with the audience. The Order, for example, started off INCREDIBLY strong (and she honestly deserved to be the main character of ch7) but has now been reduced to the repeating "my father killed the imagined, im vengeful" and nothing else. All the while Jones is somehow the one destined to face off against Geno, not her.
I firmly believe they shouldnt have plastered the seven all over ch7 advertising and made it such a big deal if The Order was going to be the only member of the seven to be here consistently through the chapter. Foundation returned for 1 season, acted completely nonsensical, and went MIA. And Order, the only OG member, has hardly been the focus.
