World-of-warcraft – Does World of Warcraft Legions purchase include gametime and base game

According to the Recruit-a-Friend FAQ:

How can I earn the free 30-day credit?

For each friend or family member you refer who upgrades to a retail version of World of Warcraft and purchases 30 days of game time via subscription or game card, you will receive a credit for 30 days of free game play.

When will I earn this 30-day credit?

Your account will receive 30 days of free game play after an upgraded recruit's payment finalizes for their purchased game time.
Note: In cases where a recruit sets up a subscription plan, their payment will not initiate until after any game time they currently have expires. This includes the free 30 days of game time that comes with the retail version of World of Warcraft.

Here's an easy way to play together right from the get-go.

Whoever gets the full account uses Recruit-a-friend to invite all of the other players to create their trial accounts.

Once you are in the game, the "veteran" account will be able to summon all of the recruits directly to him. While it may feel a little strange to be an Undead in the Tauren starting zone, you will have access to all the same quests (except class-specific ones).

And now with the advent of automatically learned skills, you don't even need to worry about not having a trainer nearby!

There is one potential drawback: Recruit-a-friend gives you all a 300% experience boost. You will gain levels very quickly, and as new players you may find the learning curve a bit steep.
