Norn are pretty tall already. My Syena is close to max height, I think, and her wife comes up to her waist at min human height. Height is subjective. I personally don't care how tall or short someone's character is unless I'm doing a jumping puzzle. Why would I? They aren't getting in my way unless it's a puzzle. Tyria is large enough to fit all of us. I myself make sure I use an asura or Gwen at puzzles, who is at min height with no fancy wings or backpieces or anything to get in the way of someone else. I like to write, so I have characters of all different sizes and shapes. One male Charr is tiny in body, while the other is larger and more burly. One prefers to tinker at his inventions, the other is more active in battle. Mount heights are interesting to look at, too. My friend's near max height asura has a larger raptor than my min height sylvari. With the same glow color, same branded skin, and one gold while the other is dark purple, they look like a male and female pair.
