It's not unique to Overwatch and applies to any team game that requires voice-chat but I'd play it (and enjoy it) a lot more if I wasn't constantly harassed by people who seem entirely incapable of wrapping their head around the existence of a woman who plays video games. Quick Play is usually fine because no one really uses in-game voice chat (on xbox at least, though you will occasionally get nastygrams in your inbox) but competitive play is an unmitigated disaster.
