In case anyone hasn't played Overwatch, the joke is that they're in a spawning area where you wait for the game to start, and that Pharah is literally blowing herself up with her own rockets to pass the time. So they're not even in battle yet.
Dunno if you're Brazilian, but if you are, don't watch the Brazilian dub. It sucks.
Netflix did such a good work with the Nanatsu no Taizai and One-Punch Man dubs, but screwed over most other anime dubs by sending to a region where dubbing work is cheaper but the quality and acting are considerably worser. :(
At least Kakegurui got a good dub too.
