Went with easiest game in the series. Usually thinks of X/Y as that. Finds some tough non-gym trainers in X/Y, though. (Some early ones: Kadabra trainer before Camphier, Furfrou double battle near Parfum Palace, Axew trainer a little before Ambrette Town, Battle Girl Hedvig in Reflection Cave.)
What trainers are strong in ORAS? Norman and Steven? Still Flannery, maybe? Could have missed some good ones, to be fair, due to being way overleveled. Played with the Experience Share in check in X/Y. Never tried it in ORAS.
