I feel like i'm the only animator who never has to use the graph editor.

agreed, if you don’t want to use it, it’s just fine, I sometimes use it more, or use it less, sometimes I just animate like if 3d were stop motion… it’s just a matter of what you’re doing, i’m still intrigued by the quality of your work =)

Sometimes the animation looks strange even though keyframes timings are right, and graph editor is the only tool where you can understand “mistakes” and clean interpolation.
