I’d say mostly Zen. Unless he lands a sick discord headshot combo. Otherwise discord can sometimes scare him off from a dive.
Baptiste has exo boots to reach higher ground or evade his slam. Plus regen burst and immortality field to fall back on.
Ana at least has sleep which if you aren’t landing on him you need to rethink your positioning or tweak your aim.
I’d argue Moira is more screwed over if she wastes fade too early or can’t do enough damage to him alone.
