thanks for clearing that up for me any chance that they will become available in the future?There are two reasons why this is the case:
1) Warforged are not included as an Allowed Rules Source for any story origin.
2) Unearthed Arcana articles are never allowed in AL, as these articles represent works-in-progress that have not been fully tested or balanced.
Lets keep the Eberron themed race in Eberron. Lets at least try to have some unique settings .
