I always think about this question, in reality and AOD.
Well, in AOD, you spend extra TC and risk revolt chances on conquered non-national provinces, while the resources and IC gain is relatively slim.
When you annex a country, you gain no tech blueprint, no better tech team, very few IC and resources, and pay TC for every conquered provinces.
Full IC take over and tech team take over are cheat like and unbalanced.
Is it possible to make conquering more rewarding?
