I'm at a biggish disadvantage with a controller and no aim assist going up against mice & men. That said, there are definitely still network issues with the game. You just have to look to see them. If hey've never effected you however, why would you be looking? Toady knows what I mean because he has mentioned it on numerous occasions where Battlefield is concerned.
But there is no debate to be had on the fact that any "infantry" on Battlefield 4 (as was in BF3) with a KD ration much north of 2.5/1 is without doubt enjoying a network advantage, for whatever reason. He just doesn't realse, or want to admit it! Either way, it's still a lot more balanced than what you console muppets have to contend with.
So do one you PS4 sycophant.
