I played a game as Ana and Genji tried to solo ult me, but our Rein solo ulted him to protect me. If you're in this group, you're the real hero this game needs.
I'm a Rein main, and I do this for any ulting people that get in my way if I have my Earthshatter ready.
Earthshatter isn't just a way to knock everyone down to get POTG.
It's also a SOLID ult killer.
Dragonblade, Tactical Visor, Death Blossom, Tank Mode, etc all get shut down if Rein hits them with their ult.
