[Prospekt's March]

There's no such thing as too many guys at the top. You need as many people as possible to be able to fit into the main event scene so you can keep your title feuds fresh an entertaining. Also at the same time, when you have so many main event calibre guys, you can book them lower down the card making the card look even better than if it was filled with mid-card talent.

I agree with this. I think it is a wise move by WWE because they have few star powers and few money matches left for WM so WWE has to try to make as many guys as possible look important to the audience so by the time WM arrives the card will look stacked.
