Was feeling bored and decided to try some symmetra attack and boy she is plenty good. Only ever see her on defence. Not sure why though her kit is more than capable of attacking.
The e shield is so amazing at making pushes if the team is having trouble and catching out injured players with the gun itself and in the current meta with so many orisa around those orbs penetrating her shield makes people less likely to camp behind it.
Not to mention having a teleport ready when your team makes the push. You can just keep the pressure going non stop onto the objective.
This is all in quick play though not sure how well it works out in comp.
