I find it extremely difficult to find a match with a party size of 2. If you get lucky and get 8 people when you start the search you have a chance. After that people drop out and it never finds anymore players before it fails out.
So far my best solution is to kill the game and start over. Doesn’t mean you will be lucky next time. Really sucks…
I can’t even get into a game by myself. This is worse than MCC
Solo isn’t so bad for me. Parties suck, they always suck on xbox one and 343i products though.
