Blizzard are putting World of Warcraft's Recruit-A-Friend (RAF) program on ice for the time being. Following the shutdown on 11 June 2019, RAF's replacement will come at some point and players will have 90 days to get their buddy benefits.
Recruit-A-Friend (RAF) in World of Warcraft as we know it is coming to an end on 11 June 2019. This is not the end of Blizzard's attempts to get more players through friend recruitment though as they announced a different system will be coming at a later date.
They did not, however, specify when that date might be and when inquired, Blizzard gave out a confusing answer where a community manager said the company doesn't have a timeframe to share with the players yet. It sure didn't help anyone that the official just said "the program will be back in its new form before you know it".
Furthermore, Blizzard apparently didn't decide what to do with pet and mount rewards yet either as the response was they don't have any information to share on the changes just yet.
If someone is looking to grab the rewards from the current RAF program, they will need to link their account to that of a friend before 11 June 2019. After the linking happens, players will have 90 days to purchase game time in order to trigger the rewards.
Those who have pending rewards they can't claim due to having all the rewards from the current system will not be able to use said reward claims in the new system. This also means that if you are eligible for some rewards but simply didn't have time to claim them yet, you are strongly encouraged to do so before 11 June 2019 or they will go to waste.
Blizzard also didn't specify whether the new system will contain any of the rewards from the current one. Technically, this would mean the mounts and pets would become limited edition if they were removed from the reward pool in the new RAF program.
