I think fall damage that seems "too low" can be explained with the PC grabbing onto roots or similar to slow down the fall. In tabletop it's easier but would be cool if BG3 also had characters falling vertically rather than flying through the air in cartoony arcs. It would be much easier to suspend your disbelief if they didn't go so over the top with it. Even better if animations would reflect trying to slow down the fall.
