It's been brought to our attention that some of you are experiencing an issue that keeps your chosen Allegiance from gaining XP you earn post-match.
Rest assured this is being looked into.
In the meantime, there is a workaround that has resolved this issue for several players:
While in the Champion menu for your preferred Allegiance, simply select to change an Item. This can be ANY item from your Armor, Spells, Weapons, and Relics options. You can even just re-confirm you current chosen item. This will ensure your current chosen Allegiance is gaining XP earned.
You can use this workaround before you select a game mode/Quick Match or while in the countdown menu.
We apologize for any inconvenience this may have caused, and thank you for your patience!
