This thread obviously hasn't been touched for a while but in case folks abandoned the game there have been many, many changes over the last few months so I thought it might be worth revisiting.
-Whole host of new customization options (changing the color of the reticule based on where you hit someone, changing the color of the RDS etc).
-There's a completely new (better) suppression system in place.
-A whole lot of netcode fixes.
-Bullets now come out of the barrel instead of your eyes so you no longer get screwed over by someone head-glitching behind a wall.
-New weapons for everyone including the much beloved AN-94.
-Gun master game mode returns.
-Giant list of weapon tweaks.
-General stability/environmental fixes. I don't get stuck on stupid rocks or debris like I used to. You also don't hit invisible walls nearly as much as you used to.
Still to come (and supposedly will be available for everyone):
-Community map (currently testing in CTE).
-DLC with even more retro maps
DICE LA has been doing a pretty spectacular job cleaning up the mess they were given. If you haven't played BF4 in a while, I'd suggest giving it a go...it isn't the same game that it once was. It took a while to get to this point, but better late than never right? O_o
