halo 3 styled infection?

I was thinking earlier today about how much infection has changed, and while i like the halo reach infection allot, I miss the way it was in 3, like the map on foundry were everyone was afraid for there life running to the top of the house, and had semi-interactive defense. back then it was intense for me, and I personally miss it, and i think it would be cool to bring it back into matchmaking,maybe in a different playlist.

Look at this

thanks
