Currently being higher friends has a few benefits. 
  • All your higher rank friends appear higher on your friend's list. 
  • We will send you a push message (if activated) when your rank 3 friends send you an in-game message. 
  • The higher your friendship rank, the more diamonds and coins you earn when you work together in rifts.
  • You can do more interesting feisty and two-player gestures.
