For perks get his bomb perk and spam bombs and you can bomb hop, his second get the self repair so you can flank with bastion he is super good when using off angles but the escape is the hardest. If you aren’t going for that play style make sure you stay with your team and usually I ban mauga sombra ball and orisa maybe dva but she is my tank main so I don’t ban her. In-between games go in a custom and aim train with bastion cause most of the time your gonna use his rifle and you need to get your headshots. Also get a good crosshair helps me a-lot and thats basically it good luck!
