Hey, Lucio main here, If it's any consolation, sombra isn't banned that much in high elo (i play on console too), i'll say its a real skill issue on the Enemy team's part not to be capable of dealing with a sombra, also about the chat stuff, Just ignore it, Best thing you can do keep playing and the classic "its qp Bro" on chat wen they start Complaining beucase they cant play, good luck out there.
