Diablo 3 Side quests list

In every act how many Diablo 3 Side quests are there? I have stumbled across a few but im not sure if i have missed any??

And advice would be much appreciated

  • Are there concrete class roles in Diablo 3?
  • Why does Diablo stop attacking at extremely low life?
  • Choosing a BattleTag, how is it used?
  • Are white or grey items worth picking up at all?
  • How does X% Chance of Finding Magical Items work for a party?
  • Should we use slow or fast weapon on the wizard?
  • We love Playing Games, especially Video Games.
