I really think it's because developers are so focused on the kind of experience they want to create they forget that it doesn't mean other experiences are "bad." Like I'm pretty sure an 4 Humans + 4 Idiots vs 56 Idiots match isn't the Battlefield experience anyone at DICE imagined. So I'm guessing from the developer's point of view, they've got in their heads things going a certain way, so when they don't, they think, "Oh, this is really bad. Just awful. Leave this in, and people are going to be disappointed by such an incomplete, second-rate piece of garbage. Best to take it out." They forget that a lot of times, the way the gamer wants to play the game isn't the way the developer intended...and that's okay!
