AFKer == Sleeping Partner == doing nothing but holding the benefits (items)
People that need the whole team to support him is not a team player, he will never risk his benefits in exchange of your help.
Supports (healer, and most int heroes) are a crucial part of a successful approach.
Sales (tanker, str heroes) requires huge amount of cash to make himself useful ( buy tanker items) when persuing something ... hahahahahah
