Overwatch is about Hero Switching.
If a team is turtling a choke and attackers are not able to get through it. Wouldn’t the philosophy of the game dictate to choose a Hero to help your team break the choke?
RantOr is the Philosophy, We don't want to give Symmetera a "Useful" Ability her Niche is "Useless abilities". Why is that so hard to understand? We can't have every hero have useful abilities. Then Genji's pickrate would drop!
If you watch OWL matches they don’t even guard chokes.
Hanamura teams stand on the roof of the building by objective.
In London they stand on the top building behind objective.
In Volksaya they standing at the objective.
Chokes are almost always avoided in Pro play anyway.
Symmetera is about as powerful as a baby with cute wool fluffy mittens.
Which is why her pickrate has been 1% or less for 3 consecutive years.
