I thought up a helpful addition.
Search for
Name="TestHUD" Opacity= and replace with
Name="TestHUD" DynamicData="/GameData.Self.IsHated" Opacity=
Makes it so the whole thing shows and hides based on if something is in combat with you, so it's hidden when unnecessary and gives you a BIG notice you're under attack. It's a bit buggy, I'm having to turn it on manually for some reason on login, then it works fine after the first combat. I'll see if I can figure out where the dynamicdata and scripts are conflicting.
