Man I agree on the crowd control, but look, the crowd control is only insanely good if you a splash card like an executioner because fireball does not take him out, otherwise the tornadoing will be not effective because the splash card will not survive.
A splash card like executioner plus the tornado will cost too much elixer to take out the whole push. Why would you do that when you can just use things like, poison plus a building like bomb tower or poison plus any really strong defensive card?
All I am just trying to say is that tornado use is useless now when you have better options, especially in top ladder. It really just needs its damage reverted so it can be viable against swarms.
