To really understand zarya, you have to learn to play in more of a zenyatta play style.. very passive aggressive tank. But once on high charge, becoming very active aggressive. Also realize that zarya is not a solo/main tank. Once her bubbles are down she’s very defenseless besides her gun. It’s always a constant frontline/rear routine with her. Best game mode to learn zarya is mayhem. I used to hate playing her then accidentally picked her in mayhem and never put her down. Too fun
