We’re talking about the viewpoint of Daeleryn and Sira here. So what if the Darkshroe defenders have a buff whih may or may not be apparant to an ingame character. That doesn’t change t he fact that people dearest to Daeleryn are dead during the War. It doesn’t change the fact that the bulk of Teldrassil’s population, every single being in the Interior outside of Darnassus was burned to a crisp, Elune failed THOSE people no matter if some defenders are getting a buff now.
The fact that the Horde PC can roll over them might suggest that it’s not that much of a buff after all, signifying the Dark Rangers’ impression on how much of a failure Elune actually is.
After all you win that fight from the Horde’s point of view.
