I don't mind group changes when they're needed. Such as when a group is doing poorly and lacking popularity -- but T-ara isn't. Not in Korea, and not in Japan especially. I don't understand why they NEED new members. This just seems like another ploy by CCM to stir up some attention.
I understand them turning down the ads to focus on training her but... That is a crap load of money. It seems like they're just trying to create hype for her.
