the orange drop rates have been increased for the last week or two. your drops depend partly on how you are spending your coins. you should not be hitting auto buy and let it go through tons of coins without stopping. there are all kinds of theories on exactly how many to spend before stopping but personally i let it go through about 3k coins and if there hasnt been one orange i stop it, exit out, and then go again. earlier this morning i ended up spending 48k coins and got 6 oranges. 5 of the 6 orange drops were obtained in a single 5k span of coins.
I get nothing within 50k coins. While my friends get red gears. One of them even have all gears red and start equiping his alt with reds. This game is just a joke. Worst Trash game ever player. Will switch as soon as another game come out, I am just killing time on this game while waiting for that one.
