The latency from a satelite you are getting internet from is most likely ~1 second no matter what. Its just that far out in space. In the end I don't see the US hauling a fiber optic line up from India, to Pakistan, to Afghanistan, Its just to far. Most my military friends leave wow in bootcamp in a lot of other things sorry
Bandwidth can be the problem if you use certain patch switching techniques. The lowest I have been able to get in wow is 110- 70 kilobits per second. For raiding and vent I normally average around 77 kilobits per second. I have to know all this for VPN settings involving my job. Its a looooooooooong story.
And you should have WAY more then that. Addons don't normally consume that much extra bandwidth. If your really really bandwidth snoddy then you can monkey around with hooking the addon communication function, so its called less or caches data. Generally most addons just involve reading the combat log and making shinny stuff appear on your screen.
