I'd rather have Larian actually spend their time and money making interesting content than to try to single-handedly fix the entire premise of the strategy genre. What would adding 5 control points do that would solve the alleged problem of having an army big enough to win but not big enough to attack-move in a group to win instantly?
The game already revolves around controlling the Resource Center points for victory.
Just the game would have ended before you got to that point. The problem isn't with armies that can't just stomp over the enemy, it's when you have an army that size the game still takes a dozen or so turns to end. It's highly unusual these days for any strategy game to go on till the complete destruction of all opposing forces so while it's a big job it's not a completely unreasonable one. You might still prefer more content or other fixes but I still maintain this is where the issues of an unsatisfying finale stem from.
