I find it not awesome precisely because of what is happening on your map: vanilla strong nations (France, Spain, Muscovy, Ottomans, etc.) become even more powerful as soon as you add more one-province nations around them.
WWM is funny during the first 20 years, then it usually gets out of hand.

But then, I also dislike MM policy of not adding any new nations (and even deleting some vanilla ones). I think MEIOU found a good balance on the "new nations / keep everyone in check" slider :)
