That seems very intriguing to say for an Air Defense buff/nerf, but I don't see it as a really good idea in the game. We are already so used to the fact that the Air Defense can deal a lot of damage since well, the start of the game. Why we have it so powerful is due to the powerful air troops we have implemented in the game, such as Dragons, Lava Hounds, and newly added; Baby Dragons. A level 1 Dragon can take nearly 11 hits from a level 5 Air defense, making it pretty strong for an attack. If we had it divided by x4, that would mean it would take 44 hits for a Dragon to die, and by that point the Dragon would have at least destroyed half the village. It would also cause ridiculously easy 3 stars for LavaLoonion attacks, for my opinion, it would seem very good to be inside the game. But x4 is way too little, 2x or 1.5x would be pretty good though. Nice update idea. :)
