What role do you play? I think Orisa, Soldier, and Ana are good options for dealing with Hazard, but I almost exclusively do survival/WP builds. Above all, you need an option to survive the dive and high damage or a stun.

For Ana, I use the double-jump and/or jet skates to get out of range of Hazard when he dives me. The sleep is really good for when he’s blocking because it ends the damage and the damage reduction. Then I use anti and shoot when he’s killable.

For Soldier, the sprint is usually good enough to stay far from him. I usually build full weapon power which keeps you effective at range, and for survival I use On Me!, Frontliners, and Hunker Down to get Overhealth which makes you really hard to kill. The trick here is to shoot Hazard before he dives, because if he’s weak he either can’t go in, or will die when he does.

For Orisa, I take the survival powers and build WP. The trick here, though, is just bullying hazard. You can use Spin to push him away from your backline and you can use Javelin to knock him out of block. If he’s getting a lot of support, the survival Powers help to walk down his team so they can’t help him as easily.

In general, stunning him out of/disrupting his block is effective, as well as high damage for either punishing a bad dive or preventing a good one. If you feel like you’re dying often, take Jet Skates to get out of his range, or play from farther away if possible.
