I havent played with you to my knowledge so I couldn’t tell you whether or not you mean it this way, but Im going to assume you do because I expect a lot of people do think this way.
“Making plays” can be a bit unfair to expect any given player to do depending on your rank, whether the widowmaker on your team is a one trick or tactically swapped to widow chances are they arent going to be getting a team kill every time the enemy pushes if you’re in gold. This is even more true if the hero they are one tricking isn’t an effective hero, which brings you back to the problem of balance.
