So I'm playing England for the first time,

I PU'd France and vassalized scotland in the first 18 years.

I've taken diplomatic ideas due to the massive amount of AE I'm getting and needing dip relation slots. I'm planning on stealing norway and sweden from Denmark, but I'm unsure about the next idea group I want to pick.

I want to pick an admin group idea, so do I go for admin. ideas (admin infouence policy later on for integrating subjects), innovative ideas (anglican ideas and great policies) or expansion ideas?

The English mission tree apparently requires you to colonize quite a bit, but I feel like exploration is such a waste of an idea group.

I want to mainly focus on europe and maybe trade company regions, but I also want the Anglophile achievement.

What do I pick?
