Blizzard has expanded World of Warcraft's Recruit A Friend program, a promotion that rewards current players for persuading their buddies to subscribe to the MMORPG. The recruiter and the recruit will both earn several in-game perks.
Current players can email a Starter Edition key to their friends from within the game. The new player and the veteran will enjoy exclusive benefits for up to 90 days while adventuring together. They can summon each other to their location. Furthermore, they'll earn experience at triple the normal rate as long as the two characters are in the same party, within 4 levels of each other, and below level 85. For every two levels that the recruit character earns, they can grant a level to a lower-level character owned by the veteran player. The net effect of these bonuses is that it's as easy as possible for these friends to quest together.
The veteran player will receive other rewards if the new player decides to subscriber. If the recruit purchases a month of WoW game time, the recruiter will earn a free month of WoW. If they purchase two months of game time, the recruiter can choose one of the rewards from this list:
Should the recruiter find another friend to sign up for two months, they'll be able to choose another reward from the list. This gives players incentive to keep enlisting friends for WoW. I imagine it'll also inspire a few diehards to sign up for multiple subscriptions so they can "recruit" themselves and get all the rewards.
There's been a lot of speculation over whether WoW will eventually go free-to-pay. However, Blizzard CEO Mike Morhaime said that they'd rather keep the subscriptions in place and focus on developing features to make the game more approachable for newcomers. This program is one of those features.
The enhanced leveling from Recruit a Friend should help players get ready for Warlords of Draenor, a new expansion pack offering content for level 90-100 characters. Even if you're not 90 by Draenor's launch, though, don't worry. You'll get a free boost to level 90 for one character by purchasing the expansion.
