I think some characters will always depend more on coordination then others based on gameplay, so if you will not have anyone coordinating with you on your team because you “chose to” according to some people in the thread, then in no hipoteses should the other team have that advantage.
Advantage in competitive sports are a real deal, and you can argue that dosnt exist in high elos, but how many people that play overwatch are in those?
Sometimes you are playing and wondering why you cant play the game then you have to go all the way to trying to join a group with someone on the other team just to discover that you now need to swap cause you will not be able to play your chacter the way he meant to be, you will be shutdown. Skill aside two characters will shutdown one completly in any situation they want and teams compose of only solo players will never cooperate as those who are in groups to take advantage of those situations.
Ha, simple.
