Not just the interface. The design change is just 1 thing. Players are now valued equally by every team. So you can't sign a player on the cheap from a big club and sell him on for a big profit later. The wages are really really high compared to earlier for players rated 87 (88?) or above. The new ME is supposed to give top players their due, they perform better than the random nature of the earlier ME. Not sure whether it's working or not though as its just been launched.
The big drawback of taking a club in div 4 is the player valuation system. People used to take it earlier as it's a great way to stockpile cash. You can't do that anymore.
Also, this inevitably results in risers not jumping in value as they used to earlier. Another big element of enjoyment taken out of the game which hurts the lower div clubs even more as that was the way to make money.
