The problem is always the same though – random groups love overcommitting to whatever is flashing on screen. If the flag is too rewarding, it drowns out the capture points; if it is too weak, nobody touches it.
The Augmentation fix is the most important line here for me. If logs were attributing plague erupt damage wrong, then Unholy was never getting a clean read anyway, so the nerf is more about correcting the picture than gutting the spec.
