Having done some battles with the patch, I must say that especially the fixing of the AI gunners works miracles. These guys - friendly and hostile - are really lethal now. Makes for a better experience for the player as well, if he chooses to play as TC exclusively and just hand over targets to the gunner - now the TC can rely on his mate that he will take professional care of them.
It seems that frames are a bit smoother when traversing the turret. The German version also has some additional comm-files now, in a different voice to separate tank crew's voices from incomming radio comms.
Many issues they cured I even was not aware that they were there
Patch 1 is a very good job, being done in a very fair ammount of time. Word is that the broken amphibious capacity will be adressed in the future, too, but will take them more time. Don't know if the small-stone-issue will be adressed, too. These two bugs are the only two things that remain on my list. None of them is a showstopper.
