Tenkaichi games were never balanced in the first place. Broly, SS# Goku, Vegitto, Syn/Omega Shenron and SS4 Gogeta always dominated those games. Just adding more broken stuff isn't going to change much except we might actually get some character variety outside of those 5 being used by everyone online.
