The ai is still atrocious in BNW sadly... Doesnt matter if they send 20 units vs my 3, I'm always going to win because they send units blindly to be slaughtered with no tactics whatsoever. This is what makes me stop playing everytime I pick it back up, it makes the game unbearable. This is on diety, if that makes a difference which I imagine it doesnt. They reallllllllly just need to hire an ai expert or two... Can't even play maps with oceans because the ai is even worst when it comes to water.
