Overall, I like the multiplayer and think there actually is a lot of positive things to focus on.
Too bad I cannot play it because the servers have been trash for the last 5 days… 
No player collision and I walk straight through an enemy and he is facing me, and melees me in the back because the game thinks he is on my back when he is not.
I can ignore the progression system because the gameplay is fun when it works. Taking weeks to add in playlists is just a joke and I don’t even care to hear why it cannot be done. It should have been done, period. BTB is fun, but only 3 maps too? Ugh.
I have 697 of the MCC achievements and will grab the final 3 when I find the friends to help with the annual achievements lol - I love this series to death, but 343 had 6 years to produce a clean launch product. Server issues should never exist on an allegedly 500million$ game, period.
