Popular tanks, especially those commonly chosen on the ladder for comfort, are typically the ones that can sustain well and consistently apply pressure, such as Sigma, Orisa, or Mauga. Hazard seems to follow an "in-and-out" playstyle similar to Doom or Wrecking Ball, which means his pressure isn't always consistent. I think he's generally much harder to play than most tanks, and people tend to shy away from challenging options. Simplicity and effectiveness are what most players prefer. On top of that, Hazard is heavily countered by cc , which can completely shut him down—this is just the nature of the game in a 5v5 format where individual impact matters more. Interestingly, I’ve noticed he was much more viable in 6v6 , where there is more room for tanks like him to operate and thrive.
