So it seems today's "What on earth goes through the mind of overwatch players" is teams that completely change the comp from what was working in the next round. Not just in a "We're defending now so we have to play more defensive" way, but in a "We're going to go from a well rounded something on attack to a dive comp on defend" kind of way.
Not sure what goes through overwatch players minds some times, had a game today where we had two snipers and not one of them could deal with Pharah
Edit: Oh, plus the ongoing issue of DPS players that don't know how to shoot things that are right infront of them.
Edit Edit: Like, I have to as a D.Va need to neutralise their Mercy? If I can kill her then the soldier or reaper on our team should be able to... why aren't they?
