I had early access to the P.C beta and I've been playing it rather a lot. Things I like:
Movement feels very fluid, comparable to C.O.D.
Hit detection (On P.C) is perfect.
I have experience with web based server browsers before (iRacing) so the Battle-Log type system isn't something new to me. It's extremely fast, clean, exploding with features and easy to update from DICE's end.
