I agree with you. It makes us like a freaking moron. I spent all my leftover 800+ gold when I stuck on 9 crystal eiffel for 2 days but yet not given the 10th crystal eiffel. All I got are concretes, tank eliminators and stupid tank. They should make the drop rate better when we use gold option. Poor marketing of the company, if they make gold option better chance of getting 10th crystal eiffel, I am sure that more people are willing to spend as people know that they can get the last crate with 300 gold or so.
