I've seen a lot of Defenseless accounts with varying degrees of walls, traps, and some with Teslas. However, given the low war weight of Air Defenses, should they be added to a "defenseless" base at some point?

I ask because my clan's defenseless acct was attacked in last war with an all (low level) loon raid. With 4 ADs it probably would have only given up 1 star.

Edit: I also see a lot of mass drag attacks by TH7s on the defenseless acct. They are wasting elixir, but 4 ADs would turn back some of those attacks too.

Thoughts?
