IDK all the health values after Season 9, and also whatever the Hell Tank health is now anyway, but she’d still have less health than Bastion by far, and maybe less than Torbjorn depending on how effective armour is.
I’ve heard about this, I think beams have extra damage resistance, but that’s just unintuitive and it’s not stated anyway. I was thinking of giving D.Va some extra, personal beam resistance anyway, just as an example.
