Here is an idea for buffing the common ADC

ADCs are meant to deal consistent physical damage over time using autos and a few abilities from range, and take towers and other objectives quickly. To me, damage seems fine once items are gotten, so not much to fix their except maybe pricing or a few scalings.

But the bigger part is their tower killing ability.

ADCs are tower takers. They are designed to take structures faster than most of the other champions in the game. But currently, other champions are doing their job to almost an equal amount. And since ADCs are one of the squishiest, defenseless champion groups in this game, players are getting encouraged to go safer, more "defensive" champions, many of which are not ADCs.

So to fix this, why not make towers have a specific trait.

#Ranged auto attacks from marksmen class champions deal normal damage while all other forms (melees, AP scaling autos, abilities, spawns like voidlings, items, etc...) deal a reduced amount.

This way, the ADCs keep their role and "need", and while not totally becoming a necessity in every game, they are a far better option than just the "play whatever because it likely will be better than any ADC besides Caitlyn, EZ, Vayne, Twitch, and Jhin" bot lane mindset we seem to be currently be moving towards.
