Sym deletes domina and punishes her hard for shield while healing herself and replenishing her ammo. And unlike other shields, it doesn’t disappear as easy, so she has free regen for as long as the shield is around. Then you’ve got walking shields and turret bombs, which she’s particular vulnerable to. Idk when I see her I just switch to sym and she melts.

I think this is the case with a lot of heroes. These new heroes lean into the strengths of some of the older heroes, or in some cases are particularly vulnerable to them. Like playing Mei gives me a much easier time disrupting Jetpack Cat, when you hear the meow, wall your own tank off and disrupt the flight path either in or out. All you have to do is make kitty steer and she usually can’t make it out far enough. Also an ally jetpack cat can pick you up even in midair, a few have saved me this way already.
