I really quite like Orisa - but then again, I main Reinhardt.
I think the game really did need another main tank, although Reinhardt still does the job better than anyone else if you're getting countered as him and you're main tank Orisa seems to work pretty decently in his stead. She combos really well with him and other characters too - in fact, she's my go-to in competitive when Reinhardt doesn't work.
That being said, what do you all think about the new skins and dance emotes?
Alone at sunset... And there the sea I found,
Calm as a cradled child in dreamless slumber bound.
