I think the game really need some improvements in this feature!
Its possible to get used to recoil and use full auto correctly, so is to single fire (or tap fire) even with rifle set to full auto.
Burst fire is the problem. If I try to use short bursts, at the end of every burst the rifle shake too much. This is so different from all other modes and from all other games that is doesn't feels correctly.
I think bust fire should be more manageable.
