Another suggestion for the Devs on Hosting.

Ok when you setup a server you should be able to select different game modes with what ever map you choose in a Rotation list. Example: Halo MCC setup:

Map: Firestorm Gamemode: CTF
2. Map: SIEGE OF CAIRO Gamemode: Conquest
3. Map: Breakthrough Gamemode: King of the Hill
4  Map: NEW SOBEK CITY Gamemode: CTF
5. Map: MANHATTAN BRIDGE Gamemode: DeathMatch

Number of Games in Rotation 5 max.

Now I have been running Game Servers since Starsiege: Tribes back in 1998. Ya I'm an old fart lol
I have always ran game servers. I do have a pretty good Idea how game servers are setup.

This is just my 2 cents worth.
