It isn't semantics, it's just simple math. Like, you can be salty on internet forums all you'd like, but it's factually true that if you consistently perform well on an individual level in your games, this will directly translate to higher win rates. A single player in Frontlines does not matter as much as a single player in CC, but that isn't the same as saying they don't matter at all, or that they have no control over the game.
