Support Guide

Hello, I'm Tsunami10, and I am a main support with Sona. There are starters that keep asking what a support does, buys, and other stuff. I'm here to show what I know about them, so if I miss something, message me and I'l update this guide :3.
What is the support ? What is his function ?
These are the basics things about a support:
It stays on the bot lane with the ADC, helping him on killing the enemy ADC and protecting him. He don't farm, or get kills: it goes all to the ADC. Why ? Most of the supports don't have the power to kill, so it only protects the ADC. What a support do that is important ? If you didn't took the protect ADC meta seriously, choose other lane: the ADC is essencial on team fights, and he must have the build and good level to cause damage. But, taking the ADC protection off, you get to ward the map: vision of the map is essencial for your team, in order to don't die or let the other team get the dragon/baron, steal blue/red, and others.
