So I notice the high elo people basically used ad carries. I guess they are the ones who will be most likely to get the penta kills and crazy farm.
What is the best ad carry in general?
Or what are the top 5 ad carries?

It is widely accepted that Vayne is the best ranged AD carry, followed by Caitlyn, Graves, and... oh, I forgot. But those three, and a few others.

Vayne is the best without a doubt. Caitlyn follows close behind, in my opinion.

What's up with everyone saying cait, she's outclassed by most AD carries nowadays.

because all you can play is cait doesn't mean she's good

id say a good riven can carry pretty hard, a good yi can carry hard, trynd, vayne, cait, graves,talon,

vayne cait twitch graves ashe

Cait or Twitch
