Friendly Fire Question

Can anyone give a rundown of every playlist (past & present) and whether or not friendly fire was/is enabled? I know about certain ones, but I don’t play every playlist often and I easily forget to test it

I personally wish friendly fire was on for everything all the time, but if it won’t be changed, I’d like to be aware at least.

The general rule seems to be that Friendly Fire is disabled for Slayer gametypes and Spartan Ops, but enabled for Objective gametypes.

I have not played every playlist, but my experiences in the ones that I’ve played seem to bear this out.
