I mean comparing it to Red Orchestra 2 is a bit weird considering if you know anything about that game, yes I even agree I way prefered playing against bots but the gameplay is vastly differen't to a Battlefield multiplayer experience. Its supposed to capture that feeling of progression and sheer onslaught of the red army charging at you in the thousands. But that game had no real multiplayer support for ages so you kind of had to play against bots anyway due to the bugs. Yet again 3kliksphillip isn't exactly known for having good takes.
Idk I couldn't imagine playing Bf3 or Bf4 against bots, like how are they going to handle the vehicles etc. There is only so much mindless mowing down of bots running at you for hours going 150-5 before you get bored of it. Yet again I am a very competitive player.
In my mind it would be like adding bots to Warzone.
TL;DR lets see how they are actually implemented first.
