Good adc?

Lucian is the BEST early game ADC other than possibly Draven. But draven is risky due to his lack of mobility. If you can get very good with lucian you will be able to outplay people hard. MF is also strong early game, but subject to ganks. IMO the top adcs to learn are.... Lucian, Kalista, Vayne, Corki. These 4 champions are a great mix. If you can learn them well you will become a very good ADC because.... Lucian is all in, giving you the play making ability and knowledge. Kalista is about making a play with knockups and is a great champion at kiting; mastering kalista will give you great adc/rightclicking mechanics. Vayne is a great late game/anti-tank champ that is necessary to learn. Corki is a longer range poke AP adc. This is sometimes necessary with an ad heavy comp, he can also make plays with his package, and can easily follow up a big engage or escape assassins. Corki also has one of the highest bursts of any adc in the game. gl, im a support main, so i pick up on adcs because i deal with them all the time

Quinn is a pretty damn good all around ADC if you can play her well.

Strong early game (usually), transitions into a good mid game, with a strong late

Ezreal (in comparison to V/J), Lucian, MF....
