This might be a good opportunity to show an issue the current method for vertical exaggeration on points when there is vector data associated with that. Here is a figure:
On the left are points that are vertically exaggerated (Properties panel → Transforming->Scale) with the arrows being a glyph using the vector data on the points that is NOT vertically exaggerated. On the right is when I applied the same Z Scaling as the points on the glyph filter (using vector data). There is no right amount of scaling the size of the glyph arrows that allows you to properly visualize these vectors.
