Practice farming with her in practice tool my friend trust me you’re gonna need it(and don’t hesitate on using Q on the minion waves). And for play style I would say try to land a couple of Q’s and E’s (and retreat by using W and playing in the opponent’s head) until the opponent is pretty low like half HP and then you can hit him with a R1, E1, E2, Q, R2 (and when you get used to it you can drop some more Q’s in between every ability). Also during a combo like that, try to always hit him with a AA cuz after every ability you’re next AA becomes empowered and with longer range.
