I think Supercell should make a Flare Spell. This would distract only Air Defenses in its radius. So you drop the spell a dragon enters it and cannot be hit by air defense but when it leaves the spell it can be it by a spell. I think the Spell would last 20-30 seconds. It would be in Level 6 Spell Factory and would cost 50,000 per spell. With 4 level each level increasing in length.
