Zazie has put forth the proposition that all men are NOT created equal and rr80 players should be able to fly for free.
I would like that. I am very close to 80. But, it's not what I want in my heart. I think rr80 rewards should be limited to very special, very awesome things. And, while flying for frees is nice, it's just that. It's nice. I don't want nice, I want FUCK YOU, I'M RANK EIGHTY AND YOU'RE A LOWBIE PLEBE PIECE OF SHIT, NOW GO HOME AND GET YOUR SHINEBOX.
My suggestion: class-specific Companions.
There are very few available Vanity Pets in-game and owning rare "escorts" that follow the Great Champions of this WAR would be something special.
