So I get that the idea is the same as LoL in that you want to take towers down and destroy the enemy base and that gold comes from kills and last hitting.
But beyond that... what's the deal with the courier? How does it work? What does that vendor in the middle of the jungle do? Who are good champions to start off as? What's the meta for the laning phase - is there a jungler in DOTA2 for example? Any good sites for recommended item builds?
