One more thing I want to see, which was the biggest oddity in Wildlands for me: I want the squad to attempt to avoid detection, not just be invisible to the enemy, crawling right in front of them in the middle of the road.
I didn't play Wildlands that much in solo mode but I completely agree with you. It really did kill the immersion for me to see my AI squadmates essentially be unseen apparitions to the enemy until I opened fire or ordered them to fire.
