How to beat Janna as Renata Glasc: the early game

Levels 1-2 favor you: Janna is a disengage-and-poke support with no early kill pressure, so your W-engage plus Bailout makes a level-2 all-in threatening. Bait her charged tornado, then commit once it's spent. Her gust knocks your carry out of the tether's follow-up, so commit only once it is already spent. Mark her with an auto for the chip in between, and keep the shield-speed for the moment your ADC needs to leave rather than to reach anything.
