There are a lot of things that need fixing. The server disconnection is annoying when your in a game with some mates but you get kicked and need to wait 10+ minutes for another space >=/
I don't know if its because its MBT LAW is such low damage but it breaks through active protection which stops every type of explosive except Mines, Slams and C4 for a few seconds and then has a 25 second wait.
I also hope they change around the Stealth Jets to actually have some kind stealth feature. EG Take longer to be locked onto, invisible to air radar or just change them into BF3 Jets because they actually had a roll other than shoot down Aircraft and fire Guided Missiles from time to time. Also use the 25mm Cannons they are better than the 30mm do the same damage but has a much slower fire rate than the 25mm.
It annoys me when they give updates like this saying they are working on an update then in the comments there are some saying "Fix the game!" and I just think obviously that is what they are attempting to do here... Some people I understand can be pissed off paying 40-50£ on a game then another 40£ for Premium and its a broken game basically but the fact DICE are attempting to fix things just pisses me off when people complain constantly when they are informing them of upcoming updates....
