Well, the issue is people have spent real money to buy items to improve their XP percentage which was EA's strategy. So it would be poor business practice to remove that earned privilege. But if the game is suffering financially ( maybe their strategy didn't include the idea that the game would still be going strong seven years later ) I think it would be fair to introduce a new additional premium currency of some kind. Golden donuts, etc. But honestly, I'm so past spending real money on this game, I can't see buying a new currency. That's my take, anyway.
