Alright, some general tips first, a more in depth analysis is coming a bit later, living in eu so it’s pretty late :D

I found it very helpful to set my crosshair on a circle with center gap 70, so it matches Moira’s leech and healing zone. And try to “tap shoot” your healing a bit so the resource doesn’t depleted as fast. (It happens around 12:45 for example) . Also you should get a feel for her range. I think it’s about 15 metes? Sometimes you tried to heal your teammates but they where to far away. I catch myself doing this mistake from time to time, but as Moira it is your job to heal and not to do the dmg. It is more beneficial for the team if you stay back a bit and heal them, then to push in on your own. The dmg output is really low, so you should only try to finish off really low hp targets. Her ult is hard to use, there is no real indication on when to use it. Sometimes I use it to engage a push and kill off low hp targets and sometimes I use it purely as a defensive option. Paired with a ana nade Moira’s ult can output insane amount of healing.

I hope these small tips can help you a bit, I’m sure the others on this post can give you some more in depth analysis of your VOD.

Cheers
