Warning : Some people told me that they get no reward at level 5, if not you need to reach level 10 and you should get both level 5 and level 10 rewards.

This is a new legit way of earning a lot of IP and RP, by the new referral 2.0 system. Please note that you have to level up to at least level 5 to receive your rewards.

Step 2: Play until level 5, and level 10 to receive the major rewards.

Step 3: Tell your friends, go play, and have fun !
