Well there are those games too. I am usually not a healer,but had to switch when no one else was going to be one. Even asking someone else if they can be the other healer can lead to mixed results. The issue is people need to also change role as required - too many are playing just one character only. This is not what Overwatch is about - you need to adapt to what is happening in each match.This is what makes it different.
Tried some games today. It was utterly dire,its all me! me! me! gameplay. Had someone say they had no interest in trying to contesting the payload,and were more worried about stats(in competitive). Which is idiotic,as its about winning not playing your favourite character 24/7.
4 of the 6 enemy side were on the payload,two of us(healer and tank) had over 5 minutes on it. Apparently we were not doing enough damage - yes because we were busy trying to not die,and we are not DPSes. The others were more worried about pot shots or fighting the other 2 and playing defensively. It was clearly not working as most of the enemy side was on the payload. Voice chat,typed chat,voice phrases,etc all pointless.
At this point,I think I will just dip in during events. Also if Overwatch 2 is going to have the same issues,then I will probably not bother with it TBF.
