New Defense?

First and foremost, this probably belongs somewhere else, I am sorry but I also happens that the general page happens to get more trafficking. So any way, my new idea is a spell catapult. It would have the range of an archer tower, and it would shoot out spells, you could set them to freeze, lightning or rage. The catapult would shoot one spell at level 1, 2 spells at level 2 and 3, and 3 at level 4, the way you would use it is you wood fill it up with elixer, then you would select a spell type at the menu and your set. And the max amount that could be built would be 3. The lightning spell damages troops. The damage for a lightning spell would be 25% of a maxed out one (lightning spell) at level 1, 30-45% at level 2, 50-65% at level 3, and 70-80% at a level 4. The freeze spell freezes troops. The freeze spell would freeze troops for 3-5 seconds at level 1, 5-9 seconds at levels 2 and 3, and 10-15 seconds at level 4. The rage spell would boost up your defense's damage! It would boost it by 5-9% at level 1, 10-17% at level 2 and 3, and 20% at level 4. This can improve clash of clans by adding another splash defense to the game, as we only have the mortor and the wizard tower. Anyway it's a bit of a read, but thanks for reading if you get this far, and thanks in advance for any advice or intrest in this idea.
