Sand box mode for clan member against clan member
Ive read that clan members are constantly trying to teach other clan members how to fight and show them vulnerabilities in base design or attacking strategy. A mode that you can go into to be the attacker or the defense, using only the base units, characters units, ect that you have access too use but at no expense. It would not require the program to create a random base. Then you can fight freely among members. This would be helpful to find better offensive and defensive strategies, which troop combos work the best, plus you can see who is the best fighter in your clan, or who has a awesome base design. IT would be like attacking a non-clan member, you wouldn't be able to see the traps, teslas, ect. when in this mode. IT could possibly improve gem sales as well by needing to upgrade to fix vulnerabilities.
