Thanks, yes I'm aware of that little accepted-culture trick, there were many things which I forgot due to being stressed and I could have done differently had I tried to min-max stuff. But it was fun to play a province-eating-conveyor-belt monster of a country where 5 missionaries were at constant work, cores being finished in less than a year, very low revolt risk and shorter nationalism than usual(Humanism+the late game monarchy government= -15years). Only time I didn't have enough ADM was when I conquered the entire mainland South East Asia, Tibet, Zhou and Bengal at the same time(had 3-4 wars going and waited for OE to drop before I peaced out full annex). Chose therefore to make Dai Vet and Bengal vassals. That particular moment I was really pushing it.Good you made it in time.
