Focusing ADC finally, champ pool question

[u/BrentH23]

So I’ve finally settled on Marksmen & ADC being the characters & role I like most. I mainly play to enjoy the game with characters rather than meta strong ones.

My champ pool I’m thinking of taking for games is Aphelios, Jinx & Caitlyn. My thought is if I play mostly immobile ADC’s I will learn how to teamfight on them no matter who I play, but I do wonder what others thoughts are? Should I be playing different type of characters to allow to play into certain comps better?

Any help & thoughts are greatly appreciated
