Yes, I feel like Rose's solo should have been released sooner AND more songs. I prefer her solo over Jennie's so... and then Lisa should release her solo APART from BP's group content. That would be the best for all.
I was waiting for songs like AIIYL, FY and we got the amazing LSG in 2020, but now, no signs of a BP comeback...
Honestly, the wait between Jennie and Rosé's solos was ridiculous. But it just gives weight to my theory that all of them getting solos was never the plan.
