The worst thing about Black Ops 4 has to be the match making.  The amount of bugs in this game 10 months after it was released is just unacceptable.  Now before you get your list of excuses ready im talking about the multi player game.

NB:
the microtransactions work great lol. (tells you all you need to know)

Here we go;

• This lobby is not joinable
  You join a lobby the game loads it stops loading and you get his message.
• Joining a game mid-game
  and viewing the score board is broke
• Play of the game is broke:
  i actually thought it was just on PC but no its on PS4 too and doesnt display players setup
• Replays:
  Sound problems there are no gun shots if i remember right.
• Kill-cam:
  Doesnt display anything sometimes
• UI Error 62811:
  No idea how or why this happens, it happens when you join a game and then nothing.
• PC only :
  Block a player and you still see their text chat

If youve got any more add to the comments!
