I would say it is pretty difficult at first, launching into the game modes without any gear and lack of knowledge of the maps i.e. spawn points, objective areas etc. but it does get better.
The main annoyance for me is when it decides to let me play about 4 seconds behind everybody else on the game! shoot somebody thinking they are there, when actually they have just walked upto me and slit my throat already... I just don't know it yet lol!
