So for 2 days now the 12th battle in Survival Mode gave me 2 Hinata fragments. So now I have 4 Hinata fragments. Unfortunately Hinata is a 5 star ninja. To best of my knowledge, there's no current or future use for these fragments. It seems like a waste of rewards I could potentially get from Survival Mode. Furthermore, Rank Shop still vends Hinata fragments (which I don't buy of course) but shouldn't it at least become inactive or something so I don't accidentally waste points. The Elite instances probably drop Hinata fragments too if I go.

Summon fragments at least get converted into summon point. Extra Ninja Fragments just kind of becomee useless potential junk rewards and accidents waiting to happen that waste time and resources. Hopefully somethinng is done about this before several people have large numbers of fragments they can't use lying around.
