At what th level is CC less effective?
This has been bugging me for a while: everybody is so worried about clan troops being lured. However, unless enemy troops trigger the cc's range, the cc troops aren't going to do anything at all. So, CC troops have to have some of their range outside the base otherwise they won't come out, the trick is that you want to have as little of that range as possible outside the last walls.
Therefore, as TH levels keep adding walls and bases get bigger and bigger, there must be a certain point where there's so much junk that the CC is effectively neutralized, or centralizing the CC would actually make it less effective.
So I have two questions:
1. Is my reasoning correct that a portion of the CC's trigger range must be outside the last walls for maximum effectiveness?
2. At what TH level is a centralized cc's range not able to extend past the walls?
