The monarch point system is my favorite addition to EUIV, and a great step for the series, but I think it could use some balancing. As mentioned by others, focusing a nation around diplomacy can cause you to actually fall behind in some diplomatic areas as compared to say, a military focused nation - for example, if you spend most of your points on diplomatic ideas, you can easily fall behind on diplomatic tech, while a military nation that often finds itself with diplo points to burn will end up rapidly teching through that branch, as they have no diplo ideas to spend it all on. There's also the issue that speccing your country out for diplomacy will harm your naval ambitions, and vice versa, both being relatively unrelated parts of the game that use the same resource pool.
On top of this, you have the basic problem that you have little control over your MP generation. Your ruler is usually random, and whether or not you can find or afford an advisor who really makes a difference is largely out of your control as well.
To an extent, I think a lot of this is just a natural result of the monarch point system, and the case could be made that we should just accept this. However, all of these problems could be ameliorated if your ideas gave you monarch points. It wouldn't have to be very much - simply giving you 1 point once you reach the end of each idea group would be enough to give you a significant boost to the areas that you focus your nation's resources on. It can be rationalized as building up a strong diplomatic corps or administrative or military bureaucracy over time, that will make future actions in the appropriate field more efficient.
