Yes agreed. This is the only method I can see and that is what I use.
In my artwork there may be a group multiple items with separate drop shadows. If I rotate the group all shadows remain the same angle. I currently have to ungroup, adjust the shadow angle for each item and regroup.
Pretty time consuming!
Have you considered defining object styles for the various rotations you need?
Yes, but that's still going to involve breaking apart groups, applying styles and regrouping.
Just seems like something is missing, all other effects roatate with the object but not shadows.
I'm not having to ungroup here...
