Who here played the game before release?

I know that MLG and many other people got to test halo 4 in the closed beta stage before release. How did they not notice broken kill cams, paper vehicles, lack of custom game options, the boltshot being unbalanced, the DMR having massive aim magnetism, removal of tons of forge features, and no classic playlists?

Surely someone would’ve said something about these things? Was anything even changed from the pre-release version?
