Make Friend Party Rewards Permanent

Friends are really important in life. Having party rewards would inspire you to play with friends! The rewards shouldn't be so huge since it's permanent, but it could go somewhat like this:

1-man party - 0% bonus 2-man party - 5% bonus 3-man party - 10% bonus 4-man party - 15% bonus 5-man party - 20% bonus

The numbers don't have to be these numbers but please make party rewards permanent Riot! :D
