Well, the BF4 spring patch is here and I have to say after a quick few rounds of RUSH that it definitely changes things... I don't think I like it already, because ALL of my kits and vehicles have been reset (yet again, thanks for that @DICE). On top of that, the tracers are utterly ridiculous now and are totally distracting from the game - I would expect some type of a patch to correct that issue, along with a few other minor issues I spotted whilst online.
Take a look at the patch notes here: http://battlelog.battlefield.com/bf4/forum/threadview/2955065242469867843/
Hop on and play a few rounds and then report back here and let us know what you think!
See you on the battlefield, SOLDIER!
