How to beat Renata Glasc as Janna: the early game

Renata owns levels 1-3: her Q Handshake root-and-drag can pull your ADC out of position for a lethal early trade and W Bailout makes her aggression low-risk, so respect the Q range, hug minions, and hold tornado purely to interrupt her drag. Her root can drag your carry out of position before you can react, so keep the wave between you and shield preemptively. Hold the tornado for the moment the tether lands rather than before. Push while it is on cooldown, and never let your ADC stand in line with the cast.
