ADC Basic Builds: An LGS Guide

My wife recently has gotten into playing again, and made the astute observation that I'm absolutely horrible at recommending item choices mid game.

Wife (playing as an ADC): So, what should I buy?

Me (dodging skillshots): Um, I dunno.

Wife: That's not really an answer.

Me: What's on the recommended list?

Wife: Boots it is, then.

After the Game

Me: So, what did you think?

Wife: I was sort of squishy.  Like I died over and over and over . . .

Me: Well, what did you buy?

Wife: . . . and over and over . . .

Me (looks at items): You bought boots?

Wife: It was the only thing I could afford.

Me: Six pairs of Berserker's Greaves?

Wife: It was on the recommended list.

With that in mind, I decided that it'd be worth it to talk about the best item paths for AD carries.
