At the baseline blinks will take whatever they get. Any type of music is welcomed tbh but when the group was in dire need of music YG gave them only 4 songs after a year and a half. Then he decided to give Jennie a whole solo. I don't care about others but there was a definite favoritism back in 2018 and YG is always known to that with his groups.
Now BP already had a lot on individuality among members and the fact there are only 4 attracted different types of fans by each of them and a lot of them hardcore bias them which tugged on the favoritism card even more back in the day and YG even capatalized on it by mismanaging BP. All he had to do was when Jennie had her solo he could have let the other members take up other activities but nope you barely even spot them considering BP barely interacts with their fans in the first place... so obv there was more division among fans and that just continued...
Now every individual fansbase and a lot of blinks only think it's fair for the other girls to get their solos as well because they very well deserve it.
Literally no one is going to say NO to more OT4 but with Yg its always this or that and the solos were due anyway so I dont think it's wrong to want it...
Also the group comeback will happen when they want to make it happen. If we don't ask for solos it's just another long hiatus...
