Unresponsiveness, lag, delay, and all the other crap we have to deal with playing this game. Servers are taking the battering so far this year(as well as previous years), but I think the Frostbite is to blame as well. Its well known that the engine is difficult to work with, from a devs point of view. I think the problems we face is not going to go away as long as Frostbite is the engine. Thoughts?
