If the team is split doom can dive in and kill supports, if the team is together dooms landing multi punches and multi slams and building up juicy over health while DVA can’t stop him

Orisa cant do much besides survive and some CC (and reminding people that shooting the tank all game, is not a good idea).
Yep. Not fun to play and not fun to play against. Simply just surviving/not being affected by stuff is a boring interaction. That’s why when she’s powerful and in every game it’s a snooze fest. If you have fun playing Orisa props to you. I think other tanks have more interesting interactions than a cc immunity button
