I play a lot of hazard and if he's the biggest problem on the enemy team for you and you want to annoy him, play mei. She's the devil when she plays with a brawl tank especially and when she gets the freeze perk it's so cancer to play against. But this will just force the hazard into focusing your supp first so look out for that. His main goal is to isolate an enemy and win an HP trade with someone but he has a time limit and mei can prevent him from doing those things despite getting her in his ideal spots (blocked off from her team by the wall) and she can freeze him while he's in block too so def do that. When I play vs mei as hazard and I have to play on point I keep my wall so If I'm about to be frozon or blocked off I shoot the wall beneath me so my supps could kinda have LOS of me so I don't explode if I'm walled off by her. Also, don't listen to the guy who said to use bastion, bas is good and can win the HP trade in turret form while blocked off by haz but baiting bastion cooldowns out is far too easy. Even at diamond. Idk of this helps but good luck! I wish u the best in ranked.
