He’s kinda mid overall right now, despite him being an anti-dive hero, tracer and genji are seeing the most play on the latter right now. When it’s not tracer and genji it’s ashe and widowmaker who out range Torb.
I wouldn’t be surprised if he got some sort of buff in the near future.
i never play dwarves in blizzard games
Practice your left clicks. He can survive Widow headshot and has no damage falloff. He can do tons of damage to any tank (some tanks require excellent timing).
Once your hp gets low, you may be finished, since he has no good way to heal himself (unlike Mei). Playing into Echo or Pharah can be pretty rough.
