Do you know how many times I've rushed banshees veil as a top laner? Too many to count. Does it help you for your lane phase no probably not. Maybe you'll have to play safer and keep Cait from pushing the wave until you can get to mid game when your tank is there with banshees veil.
Seriously, Caitlyn's not op. Is she annoying, yes. I played mostly Lucian for a while and got my butt kicked in. Then I learned what to do and what not to do (including not playing Lucian) and now Caitlyn has actually work to win lane against me.
You wanna talk about an OP ADC, let's talk about Ashe. Every auto attack is free utility. Fairly strong vision ability (making up for the lack of green wards in season 6), one of the best ults in the game gives her Ashe insane kill pressure post 6. Her Q makes her out damage pretty much every ADC pre-6. Has good wave clear with her Volley. Ashe enables her team while still be able to put out more dps than almost every other ADC. No but Caitlyn can trap you off your turret so she the OP one..
