I mean, honestly.. I think a lot of people would really enjoy seeing a battle or three in season 2. I dont mean the small skirmishes that were really good, in season 1. I mean GRAND, HUGE, battles with 1000's of people in a nicely rendered CGI, with some intricate skirmishes between known characters in the midst of it. Give the viewer some kind of idea of just how powerful certain armies are, cause at times it seems like Toranaga's army was just a whimper at best.There is a lot of actual history they can draw from, so it isn't too hard to continue the story. Even if they skip over the Battle of Sekigahara, they've got the Catholic conspiracy/power struggle and eventual expulsion of foreigners and also the stuff with the heir, since another power struggle ensued. Although that is a pretty big time skip IRL
