So this is an interesting problem which i have been encountering, I have Call of Duty: Ghosts for the Wii U and I usually play it with a friend in the split mode, I on the gamepad and him using my pro controller on our big hd tv. He also seems to struggle with the game and said it wasnt precise enough, I eventually tried it and it just seems to not control fluidly. If you press the stick slightly the crosshair would move way to much making it very difficult to aim. Not really sure if there is a workaround but Id like to hear so suggestions if anyone has some.
Thanks
