I feel sorry for Clio having to wait for so long, but I think it's a better idea to debut multiple members at once. Talents that debut together have chemistry that's really hard to find elsewhere - some of the best PC collabs are between talents of the same gen. Getting several new talents at once is much more hype-worthy than a single new talent, and people are more incentivized to check out debuts if there's several to check out at once, rather than a single one.
I'm catching up on the collab now, and they've got really good chemistry. I'm glad that it ended up how it did, it's worked out really well.
