There's more variables to this than just on the servers.
Connection issues, latency (which exists in 100% of online experiences) etc. I don't get input lag at home (where some do). It's tough to look at.
That said, camera "frame rate" issues are being addressed. I think people are mistaking "lag" for this issue in the JRC at times and that will be addressed in upcoming patch. Not saying that's the case for you, I have brought that question up to the online dev. team. They're looking into it, but again, lots of variables.
