Protected resource at expense of other 2
I know many at TH10, myself included, have felt a resource squeeze lately. What if you could protect one resource, making less available when attacked?
You designate one resource as protected, making a greater percentage unavailable to attackers. At the same time, your other resources become more vulnerable. The available resources could also factor into the equation to prevent people from abusing the system. Example: you can't protect more gold if you don't have enough elixir and dark elixir to make up the difference.
This will allow attacking for a specific resource, will ensuring you don't lose more than you earn. Example:
I designate elixir as protected. Instead of 20/50 percent being available, now only 10/25 can be raided but my gold and dark elixir are now available at a fair value higher.
If I find a base with 250k elixir, after subtracting my arm cost, I earn 100k elixir. While my army trains, I grab a coke confident that since elixir is protected, I won't actually lose ground when I get attacked.
