Just read this online thought i would share the info:
Ubisoft Studios are working hard to improve the TC's Ghost Recon: Future Soldier experience, including an evolution for the Respec and Challenges systems.
Following regular maintenance on August 7th, everyone with an active profile in Ghost Recon Future Soldier multiplayer will receive 3 Respec Tokens for their account. These Tokens will allow you to re-select decision points and can be used on any of your characters and will not reset your character's level.
The Challenges statistics will also be reset and revert to their starting values.This won’t affect your player’s statistics and Challenges will still escalate normally as players complete them. Challenges will then reset periodically, depending on the pace at which players complete and escalate them.
In the future, you will no longer need a Respec Token to reselect decision points. The method of performing a Respec will remain identical, but the game will no longer check for a token. You will be able to Respec at any time through the Gunsmith section.
