Changes from old MFLR:

Cancel governing cost from development.
Replace governing cost reduction in court house and state house , into other effects.

Increase base power generation from 3 to 4.
Ruler power roll from 0-6 to 1-5
Increase base max power saved from 1000 to 1500.

Reduced price and effect of manufactories.

Buff Confucian and Mandate.

Cost of Gov reform do not increase by tier.

Cancel missionary maintenance cost.

Province building slot unlock for every 6.666 development(0.15 slot per dev).

Incerased gain and effect of Innovativeness.

Increased overall institution spread.

Other minor tweaks.

New changes by me:

To simulate the progress of mercenaries replaced by professional army in history:
Overhaul army professionalism mechanic with a more powerful effect while harder to keep.
Increase yearly AP gain from drilling to match the new mechanic.
Add yearly AP gain for all MIL idea groups except naval group.
Remove all mercenary buff from all idea groups.
Minor tweaks around AP.

More leader without upkeep from Gov rank.

You get in total 10 idea slots at ADM tech 27.

Reduced base force limit from province manpower from 0.1 to 0.06, and force limit from buildings from 1 and 2 to 0.6 and 1.2.

Reduced base manpower from development, from 250 per 1 manpower to 100 per 1 manpower

Idea groups changes:
Replace all mercenary related ideas into other buffs.
Replace naval ideas in quality group into land buffs.
Tweaked aristocratic group to make it more millitary.
Slightly nerfed quantity.

Nerf CCR in administrative group, while add other administrative buffs to other ideas in the group.
Add CCR in spy group, in total you can still get same amount of CCR to do world conquest.
