Most people who are playing past 1600 are playing a WC attempt or a blob, map painter game, so yeah, it is very important.i just dont see it im often capped at 999 admin taking tech way ahead of time in the 1600's and im never vassal integrating at that stage of the game. Dip is better spent on dip dev
I mean, you even said it yourself, most games are over after 1600. The only reason to play at that point is for a WC or a blob attempt. So I don't understand your argument...
