@Eab I think the needing buffs is a sticking point for a lot of people. I know it is for me. Needing to use a month of stamp card SC or half an event just to 2-star skip a challenge feels really bad. Most would probably end up doing it eventually though if they were stuck with a black unit they couldn't level. Though those with a black probably spent for it and throwing a few SC for buff wouldn't be as big a deal. I think it's more a nod toward freemiums who can't level their Saki or rerolled starting black unit.
