Those results are not speculative. You can assume those minimums because those are the MINIMUMS. I am just about to finish my star season and I'm going to now get 2 Stars, and 400 credits because I was unlucky enough to end an hour before this was released?
You should have at least tiered credits based upon the minimum price of the card for the season tier you are in. One Star + the minimum for that card might be acceptable. You gave free-players a way to get cash, sure...but a well-thought out way? No.
I know you are probably just sensitive to the critiques by users here because you helped create this game...but no offense, if you don't listen to customer feedback, then you are going to keep releasing crappy products and updates.
That being said, thank you for the player lock feature, enhancement feature, etc...but anything involving credits/money in this game should involve better decision making on CD's part to maximize profit for you and enjoyment for us (and that's ultimately where profit will come from).
