If Symmetra can't have auto-lock, why can Winston?

The thing is that Symmetra isn’t good, and when people get killed by it they are salty. However, Winston takes a lot more skill than Symmetra, and no one can deny that. You have to know EXACTLY when to go in. As Symmetra, you can pretty much just go in as long as the team is going in and be fine, but as Winston, you have to know the exact right moment to go in. There is a reason Winston is played a ton in GM and not Symmetra, where as Symmetra sees a LOT more play in lower ranks, where Winston doesn’t.
