I just hope they bring it back with their next update. HC KC doesn't really help at all even though it's more interesting than TDM. They should've went for a mixed KC/TDM list and given us more real objective-based modes.
Our Black Ops server always had HC HQ, HC S&D, HC Demolition, HC Sabotage and HC CTF running.
HC HQ and HC S&D both being in there twice as much as the others and always switching between HC Demolition and HC Sabotage.
It made the game enjoyable and worthwhile, great fun for two years. We even had all the DLC maps running.
Now? Playing with friends is a pain and it seems like I'm always playing the same maps over and over. It really feels like I only get the same 3-4 maps per week.
