Lockdown back to Mixtape and more variation

Hi, could you consider bringing back the Lockdown mode to mixtape (and if it has to replace an existing mode, maybe take out Gun run?), I think it was the most fun mixtape mode and really miss it. Also, could you consider adding some more variation to mixtape in general like more frequent map rotation changes (like weekly) and maybe use some maps from arenas or other POI's to mix things up more? :) I only play mixtape when my friends aren't available because BR with randoms is just too frustratring but it's getting a bit tedious with the same rotations over and over again for an entire split.
