Defiant game modes?

As most of you should know the Defiant map pack will be releasing on the 15th.When noble was released it was just one game mode with loads of game types but what should happen is when you go on to DLC and then choose Defiant map pack there should be another section that allows you to choose 1 of the most popular game types,this is just off the top of my head but:
Big team battle
Rumble pit
Team swat
Team slayer
you guys/gals can add in other game types that you see fit.
So what do you think?

I think that playlist-related posts about Reach are currently best served to be posted on the Bungie.net Optimatch forum:
