Did JYP abandon the less prominent members of TWICE?

They could have pushed the members who left more this time, but
from the company's perspective, while individual activities are fine, it was probably more important to focus on promoting stars like Ryujin, Yuna, and NMIXX's Sullyoon to keep them.
Looking at Dahyun, it's not like pushing her leads to immediate results,
and even if they had invested more in the members' solo albums, I don't think they would have blown up like that either.
