I am trying to rotate a repeated element at incrementally larger angles, but there is an elemental offset in each column so that elements along the red lines would have the same angle of rotation:

Is part of the issue my elements being flattened? Do I need to rebuild them into a tree and move elements around to get desired effect?

Thanks

Allow me to clarify - I am trying to shift the elements of each column “up” one element as the columns move left to right, so that the diagonal condition described is achieved. I would also ultimately like to rotate elements across rows rather than up the column.

You can partition and shift your list of rotation angles to achieve this result.
