Make ap items not as good (and get mages out of bot lane)

I've felt like this for a long time. As an ADC the core things you want are Attack speed, AD and crit (unless you're an on-hit adc) No item gives you all 3 and it takes a little while to get them. Whereas a mage wants CDR, Mana, and AP. Which luden's echo gives EVERY SINGLE STAT you'd want for a mage. There's no reason to why most mages should have all 3 core items at the start of the game and still be able to 1 shot almost anyone they look at that isn't building MR. On top of that, I wanted to rant about how "supports" are legit one shotting you with honest to god no counterplay (or at least it feels this way). (Brand, Lux and etc.) They legit so so much fucking damage, that the adc doesn't even have to auto attack half the time. It feels fucking awful to play against a brand that can solo your bot lane or at least get you both to 1 hp. Or lux who can snare you for a decent size away, press r and ult then you're 1 hp, while not even being in auto attack range. No adc except for maybe jhin can get 1000 AD, but you can casually get Death cap, void staff and some 3rd AP item and already be at 400-500 AP just from 3 items alone. It's honestly ridiculous.
