People that MLBed Kita Black got memed. Stamina is both the most important stat in the game (bottlenecks every single non-sprint race) and the most inefficient stat to train in the game (low output and bad secondary stat). Both of these are by design to make you want stamina skills to reduce the amount of stamina training you need. Rare recovery skills meanwhile are the most overstatted skills in the entire game relative to their skill point cost (nearly 4x effectiveness of their non-rare counterparts, which are all expensive to begin with). Rare recovery skills can't be inherited and inherited recovery skills can't compete with rare recovery skills in power because their cost:effect ratio is so massive.

What this means is that rare recovery SSRs are the actual endgame whale bottleneck, whereas Kita is just a better than average statstick. You were supposed to MLB a Vodka or a Super Creek who, together with event Special Week and welfare/borrows, would mean you're set for life in terms of stamina support. You'd also have infinite friend points because of everyone borrowing your card as opposed to stuck with a Kita Black that everyone already has.
