I've noticed that mudras done with no network connectivity are very fast, so would it be at all possible to have the mudra combinations be handled client-side, and only have the Ninjutsu information sent to network? As far as I can tell, 1 skill(Ninjutsu) being dependant on network response would cause far less high-latency/packet loss problems than 2-4 skills(Jin, Ten, Shi, and Ninjutsu).
