WTF?!?!
      

  As of yet we have heard very little on the role of hirelings in Diablo 3 except that they are now called followers and that you can have more than one at a time.What you've seen are the throw away helpers you can pick up on the field and they follow you, and are helpful, but usually die off pretty fast. They're not intended as a replace..
