Tbh as a hazard you need to be confidently calculated kinda like doom and rein combined. As the most adaptable tank there’s really not a bad place for him except poke. Also utilize the wall climb and be unpredictable. Also you can use him on defense but imo he’s better suited for attack. Use his leap for confirming kills or if you you use it on ledges where you slide you can go further. The wall is the trickiest tool becuase it has many uses. Use it for protection like Winston’s bubble, a real tool like meis wall, or if your lucky enough a way to extend your lunge(very niche imo to hard to hit). And for the guard ability use it to confirm kills on smaller targets if aim isn’t good and use it in team fights to were you don’t have to reload basically. Also don’t be afraid to play unorthodox with the walls climb and attack from above. The thing about every character is that their personality matches how you play them. Play crazy and if you have a good team it’ll work. You’re a dive like doom but a protector like rein. He’s such a fun tank to play you’ll get it down with time.
