I have no idea where these gamemodes are. 2-3 weeks before i can play these and now i cant find them 
they’ve been rotated out. hopefully they come back. slayer pro wasn’t popular but king had as many people as some of the other game types.
King of the Hill is now in Crimson DLC and Slayer Pro has been taken out because 343 is adjusting it.

If that was truly the reason then why not leave it in whilst they adjust it and heres an even bigger question
What needs adjusting? It was the only good playlist.
