Does anybody else think Halo Reach's Multiplayer is missing some vital game modes?

I'm happy that bungie brought my favorite game mode onto Reach (Rumble Pit), but it seems like some modes aren't there. I didn't see a doubles game mode, and when i played Halo 3, that's what i remember playing. And while Halo 3 did have doubles, they removed social doubles, which was even better. What do you think? Is Reach missing some game modes?

Edit: Reach has doubles, but only on arena. Which i don't like. Social doubles was where it was at.
