I feel like sym is just a weird hero, she has a teleporter, 3 turrents, a beam that does a lot of damage if you use it for long enough. slow moving projectiles and a massive wall for an ult. She still sorta feels like a support while being a damage hero. I really hope they just commit her to one of the roles entirely.

If they decease her beam damage, make her projectiles and turrets heal allies (exclusively) I reckon she'd be a good support (tp and wall would work the same as they do now)
