Mission effect only useful prior to completion?

[Xinkc]

Missions are there for temporary small boosts if you need them I think. They are not there to guide you or anything even if their bonus is mostly pointless after completing those missions. Missions do guide the AI on the historical path sometimes. For example it allows Ottomans to conquer Levant, or Mughals to expand on other Indian kingdoms, etc.

It also allows for the glorious rebirth of the Purple Phoenix and gives a great reward/guidance system.

I would love it if the mission system was completely redone. Maybe when you get a new monarch choose a goal for their reign. Conquer 20 provinces in X region or Diplovassalize and annex 5 countries. Have rewards like +2 to monarch's military power or permanent +1 dip rep. Just throwing out ideas without any thought to balance.
