For the first few months, I played in the Chaos Moshpit almost exclusively so I played a lot of TDM and KC, but also Hardpoint, Demolition, and HQ. I hadn't played those in the original BOps so it was good for me to learn to play them. The scorestreaks there come much more quickly as you can accumulate scores more easily. Recently, I been playing TDM in the lobby for the newest DLC. Studio is essentially Firing Range with a different setting (Hollywood film set) and it's been a lot of fun playing on again.
