expensive air planes

So looking through the new army books to see what they did to my British, I found something out. AIR PLANES ARE NOW WICKED EXPENSIVE! not only do they base the points off of how often your planes come in, but on what type of plane you are gonna have come in.

Here is an example. My kittyhawk planes (the cheapest I can get) cost 95 pts for sporadic air support, or 135 pts for limited or my most expensive planes being 105 pts for sporadic and 150 pts for limited.

This makes planes very valuable, because not very many people would want to waist their precious pool of dice to stop other peoples air planes, since they might have started the game with no more than 5 dice for 150 pts, why waste them?
