No Preacher. Using the steam provided rcon console (newest version) do as Woo suggested. In the playlist simply exclude all the regular maps and leave the new dlc ones if that is all you want to have in the rotation. And, like was stated make sure that in that console "settings tab" "server options" you set the exclude dlc to false so that the new maps will run.
If you want or when you want the older maps back in or some of them then simply go back to your playlist and in the excluded list highlight the map you want back and hit your delete key on the keyboard. This removes it from the exclusion list and back into normal rotation.
Didn't know you could delete them like that
I deleted some f the maps and applied it and still only on 1 map on rotation
I tried Harcore team tactical rotation but did nothing.Even after it said it would take affect after that map
Do you need to restart your entire server after deleting them
It's worth noting that the Treyarch Rcon does not work correctly for all, and it's the unranked servers that are effected.
Unranked servers do not use playlists, they just build their own rotations via an rcon. However people with unranked servers are NOT seeing that DVAR switch in the Rcon (under the server menu), to enable/disable the DLC.
In fact it took over 6 hours for me to see the DLC in the list of available maps. I made one HQ rotation out of it (luckily), but have NOT seen the DLC maps in the list since. Every time I run the Rcon, the DLC is not available in the map list on the left of the rcon, nor is it available under the Rotation Builder.
I was lucky in the sense that I had built that one rotation, and could therefore build other rotations/gametypes out of that one .......
In the picture below, you can see the new maps in the one rotation I did build, but once I shut down the rcon and restarted it, the DLC was (and still is) missing from the available maps.
