That Minato is comparable to Roshi, they have very similar kits just replacing the scaling stats with the dodge. The mysteries are also comparable in power level, though I rate interuption a bit higher than barrier destruction (not by much). In the end I think I'd rather use Roshi than that Minato I think, especially in china where Shisui is pretty common and scaling stats are meta defining. All in all for a premium ninja, being Roshi power level is pretty crappy, if that was offered to me on NA, I wouldnt spend a dime on it.
