This is something I thought of the other day. Me and my friends were playing competitive and their team kept counter swapping so of course we had to. And eventually it ended up with our tank and their tank both playing Zarya. And It made me think, Zarya doesn't have any like actual direct counters.

There's shields that people can use to block damage and dance around her, but like no tank directly counters her bubbles in anyway.

I'm not sure why Ramattra's punches don't go through the bubbles, I feel like they should, obviously Zarya would still get charge, but being able to deal damage to her through the bubble as Ram would be kinda nice.
