how to counter early tank rush as adc
as adc buys his ... well not very cheap items, there is a thing that rly decimates me when i play adc i start building my infinity edge/bloodthirster (i dont realy like botrk cause it i like shield from bt more) and someone runs with giants belt and wardens mail already it doesnt hurt me that they think about defense but, that they can get enough stats to literly remove me so fast, in order to counter tankyness i need at least botrk and last whisper, while my damage wont be too big (overall damage and the damage i del to tanks) if i wont buy ie and phantom dancer to boost it
what hurts me more is that those guys usualy just walk by my team like nothing happened go towards me activate their whatever gapcloser they have and just churn me down with couple of hits cause i cant heal and i cant rly build defense (jinx with randuins as first item op, rito nerf pls)
this basicaly leads to me being unable to hit ppl that i deal damage to, and unable to actualy survive any fight cause those bastards cant be killed easy, and the only person in my team that they can hurt (they hit only the adc cause they dont have damage to kill anyone else) is me
i play adc from time to time so i wasnt realy in touch with the item changes, bbut right now i just cant find anything working like it did before
could someone brink me closer with the changes ? and help me to get over thoise problems
into 
is the best option. It's got a decent build path (no B.F. Swords), scales well throughout the entire game, and offers a nice arrangement of useful stats in AD, Attack Speed, Crit Chance, Life Steal, Armor Pen and a sexy on-hit effect. It also makes you obnoxious as hell to catch with multiple active speed boosts and an active slow.
, 
, or 
- that is to say, very auto attack reliant champions with long range and poor AD scaling on their abilities (and/or very few abilities that scale with AD), the best choice is generally going to be 
into either 
or 
, depending on how much waveclear you need. You can pick up multiple Doran's blades or a vamp scepter if you're suffering without sustain, but that's the price you pay for an awesome late game. This build takes a long time to ramp up, never really powerspiking until around 7000-8000 gold, but it's pretty monstrous when it's completed.
, 
and 
- that is to say, champions with Hybrid scaling and very low cooldown abilities, 
is pretty sexy. The item just offers so much utility, allows you to poke and trade incredibly effectively, and is an altogether amazing item (provided you can utilize all of its stats).
