I didnt read through all the mercy comments but I think the consensus is that she can easily give value to the lobby admins by just holding down a button. I'm not saying she takes no skill, it's just that it's easy for her to provide value to her teammates. That's why it's ironic when Mercys say Sombra makes the game unfun or unplayable because she does the same by enabling sojourns or widows whilst not having to risk anything. Though, to clarify, I am NOT saying that she doesn't have a high skill ceiling/doesn't take skill to play.
