If your team has 2 Symmetras, and is on Defense, then your game is already won, unless the enemy team has crazy good Widowmakers or Hanzos. I play Symmetra when I don't care for playing and just need to get the loot boxes.
I avoid competitive gaming like the plague. FPS or card games or whatever. people are *************s and ******s. and that's no fun. Yes. I am a Filthy Casual. AND DAMN PROUD OF IT!!!
I don't know about Overwatch, but over here in HotS, Quick Match is basically "tryharding with shit matchmaking." Honestly at this point I question why I don't just play ranked.
