I don't blame you.
Match-making is clearly fundamentally bad. Even when there are hundreds of thousands of players online EA/DICE apparently think it's ok to use bots and often they don't get replaced during the match either.
But then, as you say, after forcing people to play against bots, they take away your kill stats though leave the death stats to add further insult.
It's incompetence that they will not admit to.
And then they continue to add more and more game modes no one asked for to further split the player base and make the problem worse.
Further incompetence.
