I am playing a game as Castille and rebels are killing my manpower because I am always reinforcing. Here are my manpower and army stats:
Max Manpower: 72,850
800 reach armies this month
3 Armies current strength/max strength
Army 1: 10K/10k
Army 2: 4K/8K
Army 3: 6k/6k (Mercs)
Every time I get close to filling my ranks and gaining MP to actually recruit more armies, rebels rise up and I need 2000 men again. This has been going on for 30 years and is driving me insane. What should I do to increase my MP so I can recruit regiments?
