Many in our co-op were left far, far behind because so many on the board were running a 100% boost all day and all night. If your board isn't full of cheaters, then it's full of people who never sleep, never eat and use 100% boosts 24/7.
There are PLENTY of cheaters but us fair players have a boatload of issues without them too. Whoever says there are no cheaters in the game is full of it.
