This is currently in game. I know you didn't get to play beta to see though. That being said, I don't feel the FOV to 100 is quite enough for some champions that have large weapons on screen.For all games ever, the dev teams need to provide a FOV slider at least to 100 degrees vertical, and checkboxes to disable motion blur, depth of field, etc. And then have the game tested by someone who's prone to motion sickness. In the little time I played Battleborn I didn't actually have any issues like this, but it bears mentioning anyway.
As for the comments on the story missions, I know there are 10 story missions to be coming out, I can't really speak on which mode they're going to be focusing on, however, pve or pvp or whether there will be drop in like Borderlands because I just don't know. Myself, I was disappointed the storymodes, so far, are timed and don't have drop-in with friends. I too was hoping for more Borderlands-esque style.
I did find myself enjoying PVP more once I got into it and understand the mechanics better but it is a LOT to look at.
Overwatch, from what I understand, is a color vomit TF2?
I know Sili was one of the ones that had a hard time getting motion sick, and that's fair.
Thanks for the comments so far!
