>Girls' Frontline
If you tolerated corpse grinding, then you can tolerate the spark grind here. However tolerating the ranking mode of Girls' Frontline events isn't a guarantee for tolerating Champion's Meet here since there is a whole lot of RNG that can happen in a Career mode run that can either cripple your trainee or make it the best umamusume you'll ever be able to make. Sure you can control it to an extent to get consistent career finishes, but the sparks that come after a career run is still up to RNG.
