MCC online needs more then a patch, it needs rewriting from the ground up to get it working, hopefully that's what is going on.
It has a few problems here and there, most of the bugs were fixed in early patches like halo 4 going black screen in some loading zones, I never did finish halo 2 anniversary but that was because co-op online was desyncing and impossible to finish.
MCC issues were multiplayer involving all the online being put together. Totally different story. Singleplayer was fine in MCC.
EDIT: Single player Had issues but wasn't broken
