What about if it is like this for example MDM is current CE, First it will be MDM1 then MDM2. It will be two CE's, If MDM1 is done then MDM2 will start and the sides will change also it was in the past but I don't know the reason why it was removed. Anyways it will be fun.
I know it used to be like that. I was gonna suggest this but it was way too farmable for APBs and such. Having this seems a lot more friendlier imo.
Example: Criminals play MDM and its done, the rest of the maps are played, MDM comes in turn again and criminals play where cops always play where they change sides and cops play where criminals always play.
