Life is too short to complain at everything. Things can unexpectedly happen, and no one is to blame. 343i is doing this all for you.
Halo 5 looks fun for me, so just treat it like a game, because that’s what it is. Don’t treat everything like it’s real life, because in video games and online, you can just leave and the rest of the world will never know what you complained about.
So just stop complaining about MCC being broken and Halo 5 not being perfect in your own opinion, just be patient and do other things while you wait, and add constructive criticism to the Beta once you play it.
