exactly. i can't imagine basing liking them just for their voice because we see them/read about them so much outside of their performances. i like my idols to be candid, funny and natural, so even if they have the best voice evar they are unlikely to go high in my rankings without that. though i certainly do LOVE it when they're also talented on top of it all..
and that explains why i'm still not head over heels with any of the newbies. i certainly love them and see a lot of potential, but i think they haven't been in the industry long enough to have that natural charisma in front of a camera. a lot of them still depend too much on gimmicks to portray their personality (which maybe is why i keep liking Haruka more, and why as much as i fangirl Riho i can't rank her above the sempai yet). but i don't blame them, they're doing really well for the focus turning entirely on them so soon after joining.
