I've officially going gem free!! I spent over 3 mountains and still stuck on 9/10 Gree Wtf... While free players are at 7/10... I get a nice 16k unit for an extra 200-300 hundred dollars! Great just great!! No more..I've been spending hundreds of dollars each month. After I use up these 700 gems I'm officially going gem free.. No more money in your greedy pockets!
