So I've haven't made this video but the guy there explains really good where to farm act 1-4. It has helped me with farming a lot. Wanted to share.
Farming Spots:
Act 1 - 4 Inferno Elite Hotspot Guide - YouTube
AH guide (most many already do some things are good tips to listen to):
TryHard: Gold Auction House Guide - YouTube
Hope this helps someone.
