Seriously don't. Save your IP and nerves and get Leona. Too often my teammates (from solo dynamic) have no idea what my passive does, or that I have no damage because Braum builds for Hp and can't 1v1 their opponents. Unsupported Braum is a dead Braum, and that's what happens.
Generally avoid at all costs supports with no damage and reliance on assist from your adc if you're bronze. Sole exception to the rule being Soraka cause she can really change a game with her heals.
