Yes, damage is in their name.
But it’s damage.
Not “Most Damage”
The definition is of damage heroes is:
It does not say Damage heroes are responsible being #1 damage dealers.
Except they do.
Roadhog is weak against burst damage…
Ana - sleep & anti-heal. Can’t take a breather if you have anti-healing
Sombra - Hack. Can’t hook or breath if you can’t use your abilities
Reaper - Burst damage
Pharah - Roadhog needs to be rather close in order to do damage. Pharah can deal good damage far away. Same with Junkrat.
I really don’t feel like explaining every single hero and how their abilities can counter Roadhog.
Dva, Rein, Sigma, Hanzo, Junkrat, McCree, Mei, Pharah, Reaper, Sombra, Ana
Besides the defence matrix, I believe.
