It's a crappy feature that ridiculously tilts the balance to the biggest coiners and brings in too much an element of luck. I would love to play a pure skill game, but none of these online games are truly that. I do feel like when I first joined this game nearly 5 years ago that it was more based on skill and effort. Perhaps Gwens were always around, but I don't remember them or them being nearly as impactful in my earliest years in the game. Now, they seem to just pop up every time the developers need some extra cash which must be at least once a month.
