Just more time consuming to keep us from playing the game. For people with limited income they make it even harder. Not a smart move. I officially stopped using the earn free credits as of today, unless they come around to their senses, but I doubt that. They are getting too hard up now.
Funny that there is other games sites that you have a way to massive amount of credits, coins, or other things to buy virtual stuff, with an easy way of getting them, but this site just makes it even harder the longer you play. Like I said above they are hard up.
Next they will triple the cost of pro shop items after this just to screw us over even more. I really like this game, but now its a debate to stay.
