For posterity mostly, but it seems the connectivity issues were fixed. You can actually connect to matches and there are games going on during normal hours - if one lobby ends, you can find another quickly, and no more constant "trying to join lobby / creating new lobby" nonsense.
Still had a couple freezes on Blacklist mode (though no more disappearing teammates) and the loading times still aren't great but this helps a lot. It actually feels like a playable game online. I'm impressed they bothered to fix it, I thought for sure they had abandoned it.
I bought this game fairly late, and other than the annoying rare freezing occurrences, it hasn't bothered me much. As for multiplayer, I so far have only enjoyed the co-op modes and it always seemed to work fine. This game is amazing, I wish there was more traffic on it.
