that's like asking for a battle royale in sims "because it's popular".
not every game needs a BR mode, nor should it be a criteria. yes, battlefield is more arcade than realistic, but they went out of their way to tell "authentic" stories for their idpol drivel instead of going full alt-history where no one would've batted an eye, you honestly believe that demographic wants a battle royale, especially when there are a dozen games who do it better and cheaper?
the only acceptable case would've been to say "what could we come up with to distinguish ourselves and improve on the formula", and fail on that merit, but this is fucking dice, shit game design is their MO. radical heights was probably better than whatever dice shat out, on top of what most people think is the worst battlefield in history.
