Indeed.
Though I find that Moira's Ult is actually more useable not as a desperate tool for a push, but as a desperate Heal. I find I make a much bigger difference healing members than to aim for enemies. Of course its big benefit is that it goes through people so if I aim right I heal and hurt at the same time. But yes. If I am Ulting, I prioritise hurt members of my own team first, weak enemies second, and strong enemies last. In fact I think I heal most when Ulting and almost only Attack otherwise (my damage orb is out 75% of the time compared to Healing orb, I think).
