A lack of servers and chock full of cheats, totally worth the 30gb download.
I have been playing it for an hour or 2 every evening for the past week and have not come across a single cheater. From 2 years of adminning in bf3 I know a cheater when I see one.
There is nearly always a well populated conquest server and besides that you don't really need anything as all the other modes are not exactly well thought out.
