The global pool will allow you to manipulate the possibility of the appearance of Great People without penalties due to happiness.
Now, at some moments of the midgame, all specialists have to be 'kicked out into the fields', because. a major city sags happily and can't afford to raise professionals to the point of building some intermediate buildings like a circus or holding public works. But small, newly formed cities are able to take 2-3 specialist slots and remain happy.
In general, it will be possible to simply put specialists in each city exactly to the ratio of happiness / misfortune and not worry about anything else at all - we are guaranteed to get a specialist in a known number of moves. Now the number of turns before birth may be unknown due to attempts to balance happiness in each particular city and it becomes unknown the moment when you can seamlessly resume training professionals in the capital, and not in a village with 5 inhabitants.
Perhaps the population of the city should be a factor in the points of Great People going to the general pool.
For example:
1) Capital, 20 inhabitants, +3 Engineer points - should be a very significant coefficient, like 2 or 2.5. There are many residents, many specialized specialists who can often and quickly communicate with each other. The city has specialized libraries, experienced professors, experienced craftsmen with 30 years of experience. The player should be interested in growing professionals in large cities.
2) Village, 5 villagers, +3 Engineer points. The coefficient should be something around 0.25 or even lower. Apart from building a new cowshed or barn, there is nowhere to apply talents in design.
