SE just wants the game to appeal to more people. If they make it slightly easier (I'm assuming the change won't be that significant) for people to get higher levels it'll bring back the community who said they didn't have the time to put the effort into working to get L75. It's all about the money, and the more people they can keep playing the game the more money they get. It's simple really.

Besides, you can benefit too, just level another damn job.
