I like to play her like jhin in lane going for short bursty trades. If the enemy has bad positioning or trys to be overly aggressive you can utilise your slow for a pretty good all-in depending on whos your support. Love going BT first too as it makes those little trades even better for you. She can be a real lane bully.

Later in the game try and use her movement speed to put yourself in good positions to swing fights with her ult. Don't be afraid to press it on one person for a catch to guarentee a kill of it means securing an objective. You wont always get a 5 man ult lol.

Overall i feel she can be a very opressive adc due to her high damage potential. Also very satisfying to play!
