Meanwhile halo 2 mcc is still buggy....

It’s funny how this has drawn away from the fact that mcc is till buggy and it’s impossible to get a game without disconnects. You won’t see me buying halo 5

The MCC is a whole different story. Fitting four different games on one disc and then switching between them with hundreds of thousands of players is pretty difficult. Halo 5 will be a single game, with no switching between titles. Halo 4 multiplayer was fine, just because something ambitious did not work immediately does not mean any future titles will have the same problems.
