If I'm understanding the OP correctly he's asking if they plan on changing leves from the focus of the game why not hold off and do it once you have something else in place first?
And that I agree with.

But I have the feeling that SE has been tracking the leveling progress and it may be that players are able to rank up faster than what they would like, so overall they may want to change to game to slow it down some.
Although I enjoy being able to level quickly I would understand if that's what SE wants to do. Just be quick about getting rid of surplus and we'll call it even.
