Why are EA doing done about cheaters?

Half the lobby is playing Halo, jump shooting blindly around corners, killing me before landing. I can't even kill a guy, not missing a single shot from like 5 meters away, jumping from a window. So jumping down from a second story window isn't enough time to kill, but leaping off the ground is?

The Desync is so bad, it really is hard to tell. Is that by design? 

I also think people are cheating with the Controller icon as well now. Maybe they're spoofing it or something. It was a Heli gunner that went 100+ and like 1 death on Manhattan Bridge, on controller. I've only seen one other person do that, and I think it's the one person that actually got banned after I reported them. They were pretty obvious with their high ping, different language characters, insanely high kills per minute.
