This is pretty accurate and I dont even like the guy that much lol.
One issue I think a lot of people are having, but don't know its an issue, is being in the air while doing combos.
Being airborne is a death sentence, yet a lot of attacks take you up in the sky. You can't dodge in the air. So if you have two missiles and a laser beam on you, and a grenade on the ground beneath you
Or if I'm Widow and I grapple to an enemy, two enemies spawn and start shooting as I'm pulling myself forward, I can't do shyt but eat bullets and lasers
So some of it is knowing when to use your skills, the other is like many others have said is wonky enemy placement and spawns.
