Yes bro, you're not alone .. Survival Trial rewards are random now and unlike before where we can get 80 Fragments of Ninjas like Guy, Yamato, Kurenai and others way back v.3.0 ..

Yes, i do agree with the part of fragments of decent ninjas, like some fragments of Hanzo Salamander and Sasuke Susano'o .. But the other fact about getting 80pcs fragments of some ninjas is not that useless, remember that the 80 ninja frags that we always get way back v.3.0 are useful for Fragments Refining, which gives Seal Scrolls or Summoning Scrolls and sure 10 fragments of Iruka .. Some of them like the other response said like Kurenai for her skillbreak and sooner or later we will get the other skillbreaks for other ninjas too and some of them are available from the fragments pool of the v.3.0 Survival Trial ..

Yeah, but well .. all versions have its own ups and downs :D .. so all we can do is go with the flow :D .. hahahahaha
