Blizzard definitely is in the wrong for keeping it locked, but literally every other comment is a complaint about it. It's a game, not a NASA spaceship. Focus on the stuff that actually matters. -_-
Well, for some people it's a legitimate problem. Low FOV can cause motion sickness in some people. I know TotalBiscuit's one of those people. I don't get motion sick that easily, but I can understand where some people complaining about the low FOV are coming from.
