The Wii U version is great, but there are still a number of fixes that can be applied that don't directly apply to the game itself, things like Partying up with friends and losing connection, having to back out to Campaign mode, accessing the Home menu, etc.
accessiign home menu in the main multy menu is fine, midegame isnt. can keep the ingame friendsystem for that, which is litterly the game looking up the friend thing for you.
PS. can you get to friend tab on pause menu, havent checked this.
It comes out on the 30 th.
It is so the game doesn't get hacked too quickly.
