We all agree with you, there is an active discussion here about this. http://community.callofduty.com/thread/200530533?tstart=30
The Devs are on that thread (Vahn).
Understood. As I have pointed out before though the spam just effects forum users, as the forum belongs to the community, and it is against the CoC to Spam. The devs are aware, people are tweeting them constantly about it.
Vahn recently pondered on Twitter about the possibility of taking out HC FFA for HC KC.
Makes me wonder why they can't just add modes like DOM or KC. But read Vahn's post in there and it will give you more of a sense of where they are coming from, even if we don't agree.
