Well, this is interesting. I understand your reasoning and see why you were looking to move but, your order seems all wrong.
If you were looking for a change wouldn't it have been better to give echelon notice before seeking out negotiations with GR, letting them know you are unhappy with the direction the alliance seems to be headed and provide them an opportunity to correct it. Hell, they probably would have given MAD a protectorate and let you fly the banner of your old AA for a few weeks while your sorted out your move.
I have a lot of respect for the alliance once called MAD, and Cirrus, your character has been one I've enjoyed reading about. I'll just say good luck in handling the public backlash that will undoubtedly flow from this decision.
