About the lag part:
The worst possible connection for Aces High is satellite. Other games would suffer equally from Dial-up, but luckily AH is still low-intensity in that respect. Satellite while has crappy ping/packet loss is hardly the reason for constant warping, I and several others are proof of that. As I tell people I fight that may ask "How did you shoot me like that?" it's because we are about 700-1500ms behind everyone else. Meaning we are a constant 1-1.5 seconds behind where you think we are (this also is true when you shoot us, angles look off).
However, even satellite is tame-able to the point of not warping everywhere, ask Worm, Rodent, SCTusk, BGB and several other WWI people I fight constantly who never notice, or it's such a small lag it's barely noticeable. To blame your type of connection/location and that alone on why you warp like a mad-man, you need to reconsider your stance.
If you use Satellite:
>Shorten the cable between the Dish and Modem to as short as possible. It should be no more then 50-75ft for best results, 100ft max. I think ours is 75ft after shortening from 150ft due to a poor installation. Went from 3500-4000ms ping to 700-1800ms
>Reset Modem weekly or after any storm or power-outage. Possibly even daily if needed.
>Make sure the dish is not pointed towards/blocked by any objects (Ex. Trees, houses, etc.)
>Make sure you haven't exceeded your daily/monthly bandwidth
If you use Dial-up you should be fine (Seen people on it who are more stable then cable comcast users), Cable/DSL is fine, Fiber-optics is fine. So there really is no reason to blame your location, it's likely several things you haven't done/fixed. During peak hours you may get worse lag, but hardly terribly warpy.
This isn't meant to be mean, but really there are always things to try.
