Why do some strategist players think they don’t have to get kills??

I main Strategist cuz i know that we’re in good hands, but the amount of times I have a Jeff, Rocket, or Loki that goes 2/10/5 with 25K healing and 1000 damage is AGONIZING.

Do they forget that they have ways to deal damage too? Why do yall think heal bottling is the route?
