The bug where players were getting Bonus XP for winning Guild Wars, will be resolved prior to the next Guild Wars event beginning.
As shared previously, this was caused by old legacy code from old Guild Wars that was never indented to carry over to this new iteration of Guild Wars.
At this stage, the team does not have plans to reimplement an XP bonus for winning a Daily War. If that changes, it will be shared.
