i don't have a lot of experience with this but i can think of a couple of things that might help. Some air forms, maybe all not sure, don't do as well indoors. You could also go underwater if you are just trying to survive. There are a few places they can't see from the air, underdark is the first that comes to mind. I agree with the other post that said play one and you will learn the weaknesses. That is true for every race/class.
