Your not. Chris' point is valid about flexibility but I'll say again, what we can't forget is having fun along the way. We are notorious for helping people and adapting to our friends. When I started out and got better with D.Va, if Greboth hadn't have swapped out for another Hero, I wouldn't have played him much. So its a bit of both thats required. I also suggest Soldier is a player we ALL should use from time to time. For example I was okay with him but I haven't used him for a while and was rusty last night and struggled to hit stuff. He is the beginner Hero but most importantly, Soldier is a hero that if all your mains have gone, he will always work in whatever team setup we have.
