Ok so everybody hates defending against the witches. They are really annoying. I hit 2502, log off for the night and in the morning I have lost 22 cups to a 15 witch two-star raid :(.
But how about using witches in attack? What is the minimum number of these expensive witches needed to 2- or 3-star a reasonably good TH 10? And what is the best strategy/army composition?
