I will be downvoted for this, but it's my opinion (ADC current situation)

I think the ADC class needs nerfs in general. I think they deal more than far enough damage, and if they want higher damage it should be the role of supports to help their dps by using items such as or buffing spells (Nunu bloodboil, Janna shield). It should be more about ADC + support working together. Right now, ADC's outclass so severely tankiness lategame that it's ridiculous. Without needing anyone to buff them.

In competitive; Casters say the worlds are very oriented about toplane. But why? To TP first. To snowball botlane. Everything is about the ADC right now. It's been years that we've been through metas where ADC's were always mandatory, and they're stronger than ever.

Why does everyone take TP? To snowball botlane, because everything seems to come down to botlane nowadays. Snowball botlane, win game.

Ofc; it's less of a thing in lower leagues/soloQ where people are less coordinated to peel for the carry/ADC's have less mechanics and positioning.

What nerfs would I do? Not so huge, but mostly the AS/lvl and AD/lvl slightly reduced on most AD carry champions. Also buff poke/sustain supports because CC/tank supports are too strong right now, but that's another story (the fact supports stacking CC such as Ali/Braum for instance are good in lane make ADC's way too safe in lategame, because why pick someone like Sona/Karma/Vel'koz supp when you can take a full CC support to perma peel to make your ADC impossible to assassinate? On top of the fact you don't lose lane anymore? That's why assassin's meta is kinda gone)
