There are definitely a lot of bumps in the road with this release. The game is beautiful, but being able to play it online (reliably) is a bit tough at times. There are a lot of components that are buggy or can dynamically break (the server, the client, the Plasma back-end, PunkBuster..)
There are multiple kicking bugs/issues out there right now, and a slew of others as well. I try to maintain a list of them here: viewtopic.php?f=50&t=4277
. DICE fixed one of them with R4 but the others remain.
They're trying to triage and work on all of them over there at DICE. They mostly work during the night, U.S. time, since they're in Sweden.
