Custom settings? Hell, the genre was built on user-generated maps and game modes, but that was all taken away to protect profits. You wouldn't want someone doing something crazy like using your game to make the next DOTA, Counter Strike, Team Fortress, or DayZ. They might keep buying your old game for a decade instead of your 10th iteration of the same fucking shit.
PC gamers have practically abandoned the entire genre because of how restrictive it has become. Funny enough, user content is how these fucking people GOT THEIR JOBS.
Not that anyone expected Titanfall to deviate from the COD model. Hell, I said pages ago that there would be no options beyond "choose game type" when people were saying things like "oh, mods will fix that 6v6 crap."
