Hello ! If someone can help me for the new mk kits system. I have the rank of "Colonel" but I can only buy mk7 kits with tankoins and I want to buy a kit with crystals. I want to know if there is a condition like I must have at least a mk6 turret and hulls to unlock the mk7 or do I just need to rankup. I have nearly 800K crystals and I want to spend them. Thanks you if you can help me. Mach1nB1dul3
