As someone who has adopted it as a replacement for Battleborn, me too.
But even in Battleborn, certain abilities would pull the camera out to a third person perspective, because in first person you just wouldn’t be able to see what you were doing otherwise.
I think playing around cover is better in third person, too. Have you noticed that jungle creeps and the characters have a different animation when shooting “around a corner”?
It seems MOBA mechanics benefit a lot from the improved awareness of a third person camera.
