IS JHIN GOOD FOR SOLO q AS an ADC

Yes is not only good but he probably is the best ADC right now. For three reasons:

1. He is strong at all stages of the game. He has a beastly early game, a strong mid game (with his potential for picks) and although he drops off slightly compared to many other ADCs, his late game is strong as well.

2. Hard CC on a basic ability is OP for a marksman. Unlike 's E, can hit his W without help of an ally. As a result, he goes well with every support, as you mentioned.

3. He has excellent waveclear. It is very easy for him to reach lvl 2 first in almost every lane.
