EA just recently announced in a blog post the introduction of price ranges in Fifa 15 Ultimate Team. At the time not much was explained as to why these changes are being made but it was obvious that it was due to fair play.
Now, EA has come forward with a detailed explanation. According to EA, FUT should be fair and fun for all, so over the past few weeks they have made some adjustments.
We have implemented a lot of changes to FUT in the past several weeks, including our decision to make the Transfer Market inaccessible via the Web and Companion App, and the introduction of Price Ranges within the Transfer Market.
EA wants to make life difficult for coin farmers and cheaters. Such people generate FUT coins illegitimately in the game via bots and phishing scams. As result, coins are flooded in the market and prices of high value players go way up.
So, vast majority of FUT players are unable to get their favorite players in the team. However, things are changing:
The introduction of Price Ranges has helped restrict illegitimate coin transfers on the FUT Transfer Market, and balance player item prices so they reflect the current marketplace, but finding that right balance will take some time – we have a team dedicated to finding that balance.
EA further said that since implementing these changes, they have seen positive signs for restoring FUT balance. As for access to the Marketplace via web or companion app, it will be back soon.
