New dark spell idea: Flare Spell

Has anyone else gotten terribly annoyed when using dragons and they just run around wherever they want? This new dark spell will fix all of that. How it works is it basically has a small radius that attracts the attacking troops (doesn't affect troops with specific priorities) to the spell area. Like the flare in Boom Beach. However, the main difference is that attacking troops will still attack all of the defending troops/buildings in the way while making it's way toward the spell.
Attacking strategies
A great attacking strategy is as I mentioned, is an all dragon rush. But now there is no worry that the dragons will run off to the sides. Or when doing a queen walk, you can guarantee that the queen will go to where you want her to go.
Defending strategies
Defending against this is not as simple however. A possible strategy is to spread out all the buildings and place defensive buildings in between regular buildings.
Stats
Level 1: 80 dark elixir, 3 secs duration
Level 2: 90 dark elixir, 4 secs duration
Level 3: 100 dark elixir, 5 secs duration
And so on
The reason why the duration is so short is because if all of the troops clump together, there may not be enough time at the end for the troops to finish off the rest of the base.
That's the new idea, the name needs work in my opinion, but I hope that this was enough to convince you to add this spell into clash.
