RIP OFF GAME!!!!! DO NOT INSTALL!!!!! The gameplay is good. But another cash grab app. F2P players have NO CHANCE. Also you guys need to give away more gold upgrade cards and rubies. You're actually forcing players to spend money when they reach diamond rank. UPDATE: CHANGED MY REVIEW TO 1 STAR. I'VE SPENT TOO MUCH MONEY ON YOU GUYS AND ONLY GET BACK JUST ENOUGH TO STRENGTHEN MY CHARACTER 1 OR 2 TIMES. RIP OFF!!!!!!!!!!!!!!!!
