New Dark Spell Idea

Mirror Spell or Reflection Spell:
This idea is a "Unique" idea! I call it the "Reflection or Mirror Spell" what its does is reflects the attacks/damage back to the defense! Does NOT work against clan castle troops or Heroes!

Level 1:
Spell Duration: 2.5 Seconds
Cost: 60 Dark Elixir

Effect type: Area Splash
Housing Space: 2
Time to create: 15m
Targets: Defenses

Level 2:
Spell Duration: 3 Seconds
Cost: 75 Elixir

Level 3:
Spell Duration: 3.5 seconds
Cost: 95

YOU CAN ONLY PLACE ONE AT A TIME!

The spell sounds pretty useless to me, to be honest. You suggest durations from 1.5s to 2.5s.. while most of the defences would just hit themselves around 200-250 damage tops. Instead of using this spell, I could just take a Lightning Spell or 2 EQ and achieve the same. Also since I'd take half the damage it's not worth it, at least it could stop the defence from hitting.
