Hot take: It's symmetry. People like symmetry, far more than was obvious when the 4e design maxim of "avoiding needless symmetry" was coined.
You don't have to look farther than the calls for a "martial controller" by plenty of people who did like 4e than to see how embedded the desire to see grids filled in and patterns matched up.
Ugh, I definitely hate symmetry. That was my favorite phrase of 4e (we did not need the various different iterations on Neutral Good Planes). I was glad that they stuck to their guns over the Martial Controller.
