After putting some more hours on Moira, I’m pretty sure I will be trying to main her. Zenyetta is one of my best character to rank up with, and I think Moira will be the same, but with gameplay that is more fun to me.
While QP isn’t the best place to really know how a character perform because of very uneven team comp. it seems to me that she will do pretty well. She has great healing, and good damage, the place where she might come up short is her ultimate which is probably the weakest of all the healers.
I just enjoy her play style a lot.
