What is up with matchmaking ?

Bunch of Xbox friends (4) in the lobby. One from US, one UK, one Sweden and one Finland. 

The problem- Party leader searches for a game, be it Conquest, Breakthrough, Escalation etc, and only one time in five (sometimes less) do all four players get pulled into the game. When it's really acting up we spend more time looking for a working game than actually playing it !

Passing the party leadership doesn't seem to do anything, nor does leaving and restarting BF6. It's getting to the point that the hassle of just joining a game is making it not worth it. Oh, also the system very seldom, in fact almost never, continues on to the next game so even if we do find a working one we have to go through the whole 'Did you get in ?' circus all over again.

So as the title says, what's up with that ?
