This would be a reasonable change if there were actually a problem. There aren't just two ways out of the President's spawn in FC. You can go west (I think making this easier might be a good alternative idea). You can jump the river quite easily and either go west from there, or go around Chiliad toward the police spawn (there used to be a Skimmer at the base of Chiliad, near the bridge in the far northwest corner of the map- maybe that could be put back for more options). You can drive to the airport with very little interference and take a plane anywhere. Pretty much the only idea that tends to lead to immediate problems is the rather pedestrian route through the armor spawn.
I honestly don't understand the "change the spawns because the current ones are boring argument". They aren't inherently boring, it's just that you need to come up with creative ways to use the spawn to your advantage instead of just robotically following the last person like a virtual lemming. I can understand the mobility argument for some spawns, but that can often by helped by (tastefully) adding in more aircraft if they aren't already easy to get to.
Sample "creative use" of the FC President spawn:
Drive to the airport. Take a plane with your security team on top. Have your security team shoot from the plane at unfortunate terrorists. Fly your plane to some interesting camping location and have a competent security member fly around with it as an escape vehicle. Camp. Get back into the plane when necessary. Maybe fly up to Chiliad and glide some Vortices off the top. Maybe get into dogfights with terrorists. Maybe fly to a good ground vehicle and go for a drive. Maybe go back to trolling terrorists from the air.
Any location you want is easy to get to from the air. How can the location be "boring" when you're right next to the airport?
