I'm wondering if there is a way to rotate multiple objects to one point in Illustrator. I already know about blending and Transform Each.
There is a nice script that can do just this called Rotate Toward Point by Hiroyuki Sato
The script rotates the objects in the selection toward the center of the foreground object.
Give it a try and see how you like the results!
This is not a perfect solution. You can't select every arrow and have it magically work. You will need to play around with the selections and run it in groups to achieve the effect.
A partial solution is to make a pattern brush:
The blue shape is dragged to the brushes collection and defined to be a pattern brush with 40% spacing. The brush is applied to a bunch of rounded squares. They were created using Object > Blend.
