Regarding packs and transfer market, I would like to start by sharing some general thoughts about FIFA’s virtual economy to give you an impression about the possibilities.
I have no doubt that most people would love having better packs, but on the other hand, I have my doubts as to whether this is realistic.
At current, the average Return on Investment (ROI) on standard gold packs is around -60 % , meaning that for each 10 coins you spend on pack, you will lose 6. Why isn’t the ROI 100 %? Basically it’s pretty simple: If it was 100 %, everyone would be able to open packs indefinitely until they found the players they wanted. At the same time, the market would be flooded with even the rarest players, meaning that their prices would drop to ~0, which effectively would remove the incentive to buy packs with real money. On the other hand, there is an obvious limit to how low the ROI can get before people stop buying because it isn’t worthwhile anymore, players prefer to buy FIFA 16 Coins. Getting the average ROI right is a very delicate balance!
In conclusion, I doubt that we will see better packs in terms of higher ROI. What I would like to see are some of the more specialized packs such as “consumables only”, “Bundesliga only” and the like. The value of a pack does not come from the ROI alone but also from it’s degree of usability.
