I would give the new system a try before singing swan songs of the AI not being able to use it. Let them roll out the stuff, give the players time for testing and feedback (maybe the spiffing brit will find nice exploits) and then patch, polish, rinse and repeat. Game is growing and with trains and supply hubs it is a good way it is moving towards.
It really is de ja vu all over again. I saw the exact same posts before the EU4 Emperor DLC was released. Strangely, all these people who keep saying "wait and see" before every DLC release are NOWHERE to be seen when the forums are flooded by complaints that the DLC broke a key feature or the AI after release.
