Air sweeper as a trap

Hey i was thinking about the air sweeper and i thought well people just go in from the other side and then the air sweeper is useless. I know they added a second one with the newest update and that makes up for the lack of direction they have but what if you didn't know which way they were facing?

Idea 1: What if when you attacked the base they were facing straight up and when you attacked and "triggered" it it would show you which way it was facing when you get in range. It would still have the same effect and you would set it to point a small direction but you wouldn't be able to see which way it was facing until you triggered it.

Idea 2: Alternatively what if they faced up to begin with and when you got into the 15 tile range it faced you automatically but in a smaller fan of area so instead of having such a large area of attack they are stuck in a fixed. I think this is a cool idea especially with the new update getting a second air because this would allow you to "lure" the air sweeper into a direction away from your main attack. Also this could really screw you over if you drop your hound in and forget to lure so good for defence too!

let me know what you think!
