There are a few threads that have some discussion about customising rooms, but looking over the top few forum pages and reading them all, none have stood out as obvious threads to get this topic the attention it deserves.
No need to flame eachother about what the options are and which one is best; it doesn't matter if you're pro or anti respawn, pro or anti the intel gadgets. All this needs to be about is if you want the ability to turn things on and off. Kill Cam, gadgets, particular weapons, weapon pick up, number of bases, number of respawns etc etc. No need to disuss them all to death again.
Just focus on custom settings yes or no.
