I still think that the fans are the ones who need to get over all member senbatsu. The announcement was in July, the girls are probably fine now. All member senbatsu didn't work at all and this is why after 4th single the group started to stagnate. Yes, is something that tied down the group but everything changes and the group has to move forward. About Techi, I don't think she is under-appreciated but the opposite. Yes, she is a great performer but is she the only great performer in the group? Sadly, the idea is deeply rooted in fans(and member). For me, when they debuted a lot of member caused most impact than Techi and it is fine, but, the center has to change because right now there are members that can be better center than Techi but they haven't had opportunities to prove it. For me, all the members are irreplaceable because they are differents and all of them give something to the group, when a idol graduates the group lost something but when other generations come, the group receive a lot too. All member are important and they deserve a chance.
