The gifting system was announced on April 8th 2016 by Zumulus.
It allows players to send bundles of Mystery Boxes to their friends.
You can give gifts only to people who are friends, using the /gift command. There you will be able to choose which gift you would like to give. Gifts that you have waiting to be given, as well as gifts in bundles already send, do not expire and will remain in the Mystery Vault forever. Before sent, they are stored in their own section, the "Gift Inventory" within the vault. Once sent, they are stored as normal boxes, but are sorted first in the list until opened. It will display the IGN of the player who gave it to you (Trivia: The name displayed will show the exact rank that player had at the time of giving you the gift, and will not update).
Once opened it will display in chat the 5 boxes and their quality.
When players receive a gift and open it, they will radiate with generosity for the next game they play.
The generosity system has been 'exploited' to create XP parties. This system is explained in more detail by Q__T in this forum thread.
There was also however a nerf to XP parties, reducing the number that could stack together. (Source).
Gift Contributor Rewards
There are 6 rewards that can be obtained after giving 1 to 100 gift packs, meaning that a "5-pack" of mystery gifts will only count as 1 gift pack being given instead of 5.
