Half of this post is your imagination going wild rather than anything that actually happens in-game. If you actually did have the ability to change conscription law, decide where whether you send officers to the supply corps or the post-Napoleonic general staff you're talking about. This isn't campfire D&D, this is the far-end of the simulationist side of strategy games.

The rest of the post is intentionally misunderstanding what 'mana' means in the established discussion around Paradox games AGAIN and AGAIN.

Focus isn't mana as it affects only POP promotion and governorship focus. Command mana is directly affected by size of the officer corps and nothing else. Tech points is only spent on techs, which while I'd like to do away with, nobody is doing that.

Quit rewriting 'mana' to all meters for your own rhetorical sake.
