Is Hepsi worse off without Gülçin?

It might be too early to say that Hepsi is a dead without the energetic, beautiful, and soulful singing Gülçin in the girl-group but
maybe not. Gülçin gained a lot of attention over "Ara Ara" unlike Hepsi with "Nükleer." So the big

question has to be "Is Hepsi over?" or maybe... "Should they add another member?" It's impossible to say the girls are stronger vocally without Gülçin who obviously had the strongest vocals in the group and after she left it seemed as if the group was struck dumb.... dancing and moving stiffly during performances and not putting very much into their act. It seems like without Gülçin a huge chunk of the girl's morale was taken away shown in the cheap performance of "Yeter" and their MVs after that. Maybe, perhaps they all might need to go solo or form their own groups.... Hepsi seems to be Hiç Kimse....
