Hey, so this has been ruled out, please read the stickies before posting

!
So, I understand that this may be kind of hard to see why this has been ruled out, so I will explain the reason I think it is ruled out. Let's begin: ok so imagine a th10 with 5 invisible spells. This guy attacks another th10, say, mabey a maxed one. Ok, so this guy places his troops on the ground, and the towers start hitting them. Let's just say for example that each spell lasted 10 seconds at its highest level. So, once the troops are near the core of the base, he places one spell. The infernos immediately stop firing. This means that inferno towers no longer serve a major purpose in the game. Moving on. Ok so after the th goes down, say the troops split up, there goes another two invible spells. He still has two spell slots left. This would make the game too unbalanced, and three stars would become more common. Overall this feature would ruin the game. Sorry man.
thanks,
