I think it's mostly related to Chain building / recovering PP while dealing a bit more damage, but you'll also need APPR so you don't waste the needed PP for PA (for ChainFinishing too) ..... once you party up, the benefit for SRollArts/Up might be reduced (or might simply nullified).
S-Roll-JA might be a go to skills before, but, I think it's not worth the SP anymore, since it only affect 1 PA right after S-Roll.
Probably kind of usable when fighting against very aggressive mobs (and you happened to be the target) or the mob simply turn around a lot (you need to do slight repositioning with S-Roll a lot) , so you can only did 1-2 PA before needing to S-Roll again.
That's about it, I guess. So, imo, S-Roll-related skills are too situational with 9 SP to lose (at least)
