The Air Sweeper, It was a good idea but implemented poorly.
Truthfully a defence that slows troop advancement is quite a good idea but how they went about it is what bothers me. Here is my idea of how I think it should have been designed.
Level 1
Slows unit movement speed by 1 and reduces damage dealt by 5%
Level 2
Slows unit movement speed by 2 and reduces damage dealt by 10%
Level 6
Slows unit movement speed by 6 and reduces damage dealt by 30%
A reversed rage spell!
Change it from a cone into a circle with the same range as an Xbow and Give it 2 modes aswell.
Set to Air it has 14 tile radius and Ground & Air 10 tile radius
We only get 1 of these buildings and for what it's worth... right now It's extremely lack luster for a single building. We've had alot of idea's about freeze traps and this is the 1st step for supercell to provide slowing defences. Not to harp on about it being 3 months but the amount of people displeased about the update speaks for itself.
