Coko. Coko going solo was stupid AF. She was pretty much solo in that group. Not to mention the group was thriving and very successful. They wasted all those years because miss hot coko wanted to he a bitch.
Athena Cage. Kieth sweat gave her the perfect set up to launch a solo mess and then she came out with those trendy microwave singles like Hey Hey etc

Azealia Banks. If she would've just STFU sometimes. She would be in another space. You can't take on the whole fucking world.
Chilli. The way usher gave her the perfect set up to come out snd reply to confessions (whether it was about her or not). I never seen anyone just stand at the finish line and still fumble the bag.
Claudette Ortiz. She has everything going for her to have a lauryn style attempt. Two Wrongs was even The perfect lean in to a solo mess. instead she went on to have 50-11 kids with that ugly ass cheating nigga.
Chrisette... no matter what the motivation was. It wasn't worth it.
