I like the new spotter eagle mechanic on my hunter, but I also miss my pet. I know the option to swap back to the pet exists, but at the cost of the new mechanic. Which is why I propose the following glyph:
Glyph of the Hidden Companion:
Your primary pet will lurk in the shadows. When you apply Spotter’s Mark, instead of an eagle swooping down, your pet will emerge from the shadows and leap at your target, applying the same debuff on the enemy.
When you use Harrier’s Cry, your pet will appear next to you and apply the same buff.
