Bear in mind that formally, fall damage is 1d6 per ten feet fallen - so you can in theory fall twenty-seven feet off a second storey building and take as little as 2 damage, or as much as 12; flavour-wise the variance being the difference between how badly you land and so on. I feel as though in the earlier builds the damage was being calculated as 1d6 every five feet, and that may have been more recently corrected, but I'm not certain on that score.
