The odds are already stacked against the attacking force. In fact, they're stacked in favor of the defense more so than we would like at this point. We're looking to address this in an upcoming patch so that defending Tol Barad doesn't feel like there's virtually no fear of loss.
In line with that design goal, we made this hotfix to ensure winning Tol Barad back for your faction feels much more rewarding.
