Is Treyarch going to ever address the lag in this game?

I thought the beta had superb hit detection and very little lag, then when the full game came out, it never seemed to carry over.

I feel like it's the only reason that I'm losing gun fights when I get the drop on someone. Consistently getting in good connection lobbies with 0 packet loss.

If they would just address it as a known issue, it would give a lot of hope to the community.
