Yeah, i'm the one new to competitive shooters.
I mean you did nothing but establish that you wanted to enter this thread and shit on people for wanting what is a widely supported option in most modern FPSs, so maybe explain yourself a little before shitposting if you don't want people making assumptions? Your first post in here was literally a driveby but I guess you turned around and decided to stay.
I don't get why people whine, this isn't a single player game.
Because again, it's not a problem in literally every other multiplayer game, and you're not going to sit here and tell me that Overwatch is such a special snowflake that they can't possibly support it.
The reasons of
1. It would make ultimates unbalanced
is wrong because ultimates aren't determined by your FOV, and
2. It gives an unfair advantage
is hypocritical at best because there are a million (exaggeration) other things Blizzard allows that gives people with more money/equipment advantages that aren't the mainstream standard.
Giving people a slightly higher horizontal view doesn't all of a sudden make them better players. A garbage player at 21:9 is still going to lose to a pro player at 16:9. If you're mad because people out there might beat you, and if you're willing to blame it on the fact that they might've had a 21:9 monitor, you probably deserved to lose in the first place.
