I always play solo and pretty often end up with garbage teams. I can fill just about any role easily except for healer, but my team always seems to think that reaper, soldier, pharah, and D.va are the only option. I've had matches where I was playing widowmaker and a friendly roadhog seemed hiding behind me is the smartest option when attacked. I've seen Ana attacking the enemy at a range where reaper would be most effective. I've played matches with four snipers on koth maps. It's really ridiculous how inconsiderate people are to the people on their team who are just trying to play a good match...
