I'm sure most of them are used to it by now. The problem with Nogizaka's current system is the classification of Senbatsu and Unders, in which Keya is trying to fix on their own. This classification conditions the fans' mindset to look at the idols in a "weak" and "strong" manner. Here's the problem, I heard before that when someone enters senbatsu(strong), she will have new jobs, tv appearances, etc. in contrast to someone who is in unders(weak). I'm not saying that unders doesn't have new jobs or tv appearances, what I mean is the volume. Now, if most of the girls in the senbatsu are unchanged (the "If it works, why change it?" principle), of course they will get more popular or in business perspective, their market value will increase. The unders on the other hand may grow slowly or the worst, "stagnant". What happens is that the gap between the "weak" and the "strong" increases drastically. I think this is the main reason why the management can't just pick girls from unders to senbatsu and I also think they knew about this problem.
