Make Symmetra a Support without Healing

[Terranguard-11978]

We currently have moved her to Defense. We tried a healer version which had her turrets healing instead of dealing damage, but it felt super awkward, especially with how fast Overwatch moves.

That said, we are playing with a new way her turrets deploy. Instead of having to stick them directly onto a wall herself, she can now fire an un-deployed version like a projectile, which sticks to walls/ceilings/etc. Once it sticks, it will unfold like it does on the wall currently when she builds them.

This helps for a bunch of reasons but one of the big ones is that it makes it a lot easier to play her on offense or just be able to preposition her turrets much more easily/quickly.

Wrecked. I like the idea of chucking her turrets as it’s smoother and quicker.
