Quick-Joining never puts players in a running match. Anybody who's coming in midway through and ruining it for you did so manually.
Based on conversations with players that have joined mid-game this is not the way things are working - no matter who says it's been fixed. I'm being told that Quick Join is still dropping people into running matches - and not just by the chancers but people I'm trusting to answer honestly when I ask them what they think they're doing joining as a second gunner, etc.
I'm also seeing L1/1/1 players dropped into unrestricted match lobbies from Quick Join - telling me it's only their third match and they're using Quick Join because they don't understand the lobby system. But I'm also finding that the AI is also playing up and occasionally doubling up an AI gunner with a player gunner, and giving an AI engineer when there's already two player engineers - and even before Quick Join was supposed to have had it's teeth pulled we were told the QJ balancing was the same as the AI balancing.
Frankly, I no longer believe that any change that's claimed to have been made is working as stated. Even with the last big patch, which was presumably project planned as a major milestone in the development of the game, there was the "
I know it says this, but it's working like this" comments over the next few days. It doesn't inspire confidence in the competence of the team.
