You don’t have to worry about one shots from widow or Hanzo, ever. Sure they’ll go for your team, but you can take riskier players knowing you won’t be deleted

You can cancel or flat out tank most ultimates. Dva, Sigma, Orisa can eat or block most dps ults, rein can block, Zarya can cleanse, etc

You have the ultimate with the most potential for team kills. That’s because most tank ults are for CCing or displacing the enemy so that your team gets the advantage, allowing for 1 ult team wipes

You don’t really have to worry too much about picking off enemies yourself - your job is to make space (by literally taking it or by displacing the backline), and to peel for your team
