With a game with as much inactives problems as this I can't see why this isn't a no-brainer.
Penalties (just concepts do not have to be these)
Extreme leavers can''t do certain maps (randomized), can't do eventzs and get tagged with an extreme leaver name (in order to warn players about allying or coalitioning them)
Medium can't do the events and also get tagged
Little can't speak in chat and increased market fee
Conditions which allow for you to leave:
You have less then 10 provinces
The match has continued past Day 8
All of your coalition allies have less then 10 provinces (but not combined)
Your maximun food/manpower production is less then 1000
You don't have any of your core provinces
Any of the suggestions in these ideas can be subject to change just as along as a leavers penalty is introduced
