For sure Clovis mod solves most of the question. Just readed his mod threads and seems heroic work for me. Do you work and MOD for hobby?
Also, if drafts dissappear, tons of money & WS are available.
So again, all the economic system is to be reworked, as Clovis propose.
I am not looking into the real history problems, you know them well for sure, just the math problems getting a final Huge army in the mid 63... I believe this is MORALE.
As designed, it is more MORALE costly to VOLUNTEER a lot than to DRAFT a lot. As everybody says in all your history explanations, it should be the other way.
As designed, we are capable of doing FULL Mobilization (compensating this morale hit- just a -1 difference- with the proper Embargo option) + 1000$ volunteering with only a SINGLE POINT MORALE LOST. Total cost can be 400.000 $, perhaps losing an extra morale for proper economic option
So... hold at 100-105 morale (thanks to other little boost events) and so an extra monthly boost +30 roughly to the pool.
So Year after YEAR we can add all this people without lowering our morale.
If Mobilization could cost 5 NM penalty extra -> Oh for sure we must think seriously on doing it every year.
Perhaps Total Drafted men should be decreased + morale penalized, while volunteers upped?
