Yeah it's sad to see a full team never push toward an objective for the whole game and be content with standing at the edge trying to get long range kills. As a Lucio or Mercy why even bother keeping them alive...
Tell me about it! After pushing the payload over two-three objectives my team couldn't help me do the final stretch (ten meters, maybe) because they were all obsessed with their Widow/Hanzo/McCree composition. It's the final push, I switched from Symmetra to Winston/Reinheardt/Junkrat for a reason, why are you still being mediocre far range shooters? But then the next game is a victory and all is forgotten. I'm not some pro-player but there's rules of the game and common sense.
