I think that's why I can usually understand multiple points when different discussions come up here. Because even though I am a mainly online player (I usually play competitive games, that's my whole background. PUBG, COD, Battlefield, etc.) I also am an MMA hardcore with Autism. So I too would love for the game to be as simulation based as possible, as I've always believed the small details are what really make something go from ggod to great.
At the same time, being someone who plays online as much as I do, if given the choice between the two things, I'd definitely choose mechanically quality over realism. It depends on the scenario, but most times I'd probably choose what was better mechanically. Though I would not be willing to sacrifice realism to an extent where I'm arguing for unrealistic things to be added to the game. I personally don't think the correction on the body shot issue was an overstep. Even if you hadn't experienced it in lower levels yet, leaving it unchecked for long enough could make it a permanent part of the meta to where you're even seeing it playing with homies (like transition faking or throwing the head kick during the stand-up animation) and that would be bad for everyone. Even still, I don't see how that would affect offline play that drastically. From my testing with it earlier, it doesn't seem like the changes made a large enough difference to "nerf" the body shots.
Gaming communities for some reason seem to think there's two ways to fix something. "Nerf" or "Buff" the **** out of it, no middle ground. There's no tweaking and tuning to get stuff to the perfect level. You either make it crap, make it godly, or take it out entirely. I think that's an oversimplification, and with a game like this you want to fine tune as many details as you can. If that means putting out a patch here or there, doing some trial and error, so be it. I honestly don't think what they did was an overstep, though I do think discussing the different mindsets of the player base is interesting.
