I hope we'll see something like Commander Battles in this, its by far my favorite game mode in NW. Being able to be an officer and march around giving orders to my dumb soldiers, fighting battles in a much larger battle. The best part about it is the ability to have massive 200+ vs 200+ battles with only 15 - 20 people in the server. I feel it would massively aid BCoF in its longevity, and people wouldn't have to wait around playing smaller skirmishes, waiting for the weekend events to participate in an epic battle, as well as giving the average joe the ability to lead regiments into canon fire. I love line battles, but im not a very good commander, so I stay as a rank & file rifleman. Commander battle gives us all the ability to participate in these huge battles as officers, giving crucial orders with the perfect timing. NW commander battles comes close to perfection for me and a lot of other people, with some easily fixable annoying bugs (lack of facing orders).
Its a shame most games just fizzle out and die because the game is built around having a lot of people in the server, and there just arnt enough people to participate in said server. Commander Battle fixes this by putting the average joe in the commanders spot, to order around 30 or so people, multiplying the one player by 30. You can have awesome battles with just 10 people in the server.
Another idea since im already here, would be the ability to split your reg up, separating 10 of your guys to go help the flank in need.
Just my thoughts. I am very excited about this game, just found out about it, looks very promising so far.
Edit: Another big fault of NW, that is sometimes annoying, was not being able to tell your soldiers who to fire at.
