Can we buff ad carries?

I dont see much of a point in playing AD carry anymore. ive been a ADC main for about 2 years not, starting in late season 4. While ive felt confident in my abilities to this point, i feel there is a severe imbalance in the game. From my POV you need to pretty much build an adc 5 damage items to get the most damage out of the champion, and that leaves you pretty squishy. You would think that having 5 damage items would allow you to kill things, but youd be wrong. Because bruisers. champions such as irelia, jax, darius, shen, etc who can build one damage item and then full tank, can kill you much faster then you can kill them. Some of you might say its positioning, but most of the bruiser champs today have so much mobility that you would have to be in your base to be out of their range. I see ad carries as champs who do alot of ranged damage over time, but what do you do when you cant do that damage? im open to suggestions on what to build against bruisers other then lord dominiks.
