Any Overwatch player will know that being 'on fire' is always a good thing, as it doesn't meant the literal, burning sense, but instead means that you're doing particularly well with a character, as indicated by a meter and subsequently flames around your character image on screen.
It's always nice to know you're doing well and, as noticed by Reddit user Terabight, now the rest of the team can hear the voice line your character says when they're on fire, meaning that everyone gets to know how good you're doing.
This change came as part of the 2.05 update, and no doubt will cause immense joy among those who love to show off their skills. Will this get annoying, or is it always great to hear your team are doing well?
