I truly fail to understand this one. My understanding is they removed the really cool looking dark aura and made that red one because they thought the dark one looked wrong on a mount. This is a problem how? Reinstate the really cool aura and then let players decide if it looks bad on a mount to them. If it does, you can turn the aura off yourself by clicking the skill off. No interface needed or special coding. Or, just have the aura not show while on a mount. I really don't get it.
