I don't know if anyone has mentioned it yet, but the flak ht was fixed and is now a murder machine. Any infantry approaches on this thing is a swift death. The projectiles are not hitting the ground early, so it's extremely effective.
I don't notice the input fix much, but what I do notice is far smarter behavior. What the UI is displaying to you is what will happen. It's quite amazing in a hard to explain way. Like that itch on your back you couldn't reach is not only soothed, but gone.
Buildings are acting very strange. I have played a 3v3 on oka river. The first engagement I saw a shack collapse. It was in the middle, Rifles in the church and grenadiers behind the truck. The little shack next to the truck must have taken some stray bullets and just dropped. No one occupied it.
You can't get near it not in it's range or your unit could die instantly. The range circle showing it's range is still unfixed so it can shoot far than what the game tells you becoming even more dangerous because your units die faster now.
I still don't understand why it has to be so powerful, it just penetrates a Jackson or Sherman like if they were butter. As if OKW didn't have enough AT power already.
