Gentleman, fellow gamers i've tried to increase my general's intellectual trait in every...single...one...of my campaigns and it never ever went above Erudite despite all my efforts/Starting traits/Academies/age.
From age of 16 coming of age i had them sitting in a city with capped 100 PO with everything set for them and it always ends up having 1 less army that i could field trying to beat DEI on very hard.
Any1 has some insight on what else can be done for the sake of Governors so they could become Socrates's toes? (atleast)
