They just went and changed things that didn't need to be changed IMO. Ask a hardcore COD player if they want the controls completely changed up on the next release... To some, I know it is not a problem/concern to them, but I simply hate the new controls. I couldn't play it for more than one round, and I have played BF series since 1942 on PC... :disappointed:
At this point unless they change it, I will not buy it. I may consider PC, controls can be anything obviously, but playing with unknowns will turn me away from that and make it a waste of money.
