They had a lot of problems on this launch which they are slowly ironing out. I dont think AE and Dice will ever fully recover from it tho.
Personally I think its loaded with Hacks. And its one where you cant walk on and do well, its a squad based game. Unfortunately they got rid of VOIP about 4 BFs ago and tho they have brought it back, squad VOIP at least, the culture refuses to allow players to use it since everyone is on TS or Skype, or whatever. So yes team work is virtually non existant. The game moves far to fast to allow useful type chat comms.
There are to many hackers, to many snipers, to many weapon types, and the hit registration code is poor. I was hoping it would turn more into a proper sim but instead it has turned more COD. At its best it is brilliant, the graphics and damage engine unprecedented, but all to often its at its worst. The BF series has lost me.
I bought it to spend time with my kid who is stationed in ND. . So for that it has worked but overall it has been a big fail.
