I feel that height has a role to play in the Altmer's arrogance and snobbishness in general. Why not, since your entire race towers over everybody else? You can't really feel superior when you are at briast level with Mirabelle Ervine.
Exactly thisI play Altmer 9/10 but I can imagine its equally annoying for Bosmer not to have a lower viewpoint.
One of my favorite Morrowind memories involves http://www.uesp.net/wiki/Morrowind:Ibar-Dad. It is the famous cave with lots of loot and the http://www.uesp.net/wiki/Morrowind:Eleidon%27s_Ward.
First two or three playthroughs I was a Dunmer. Then a Nord.
Only when I gravitated back towards being an Altmer, going to that cave for the loot, did I notice up above that brilliant shield all awesome looking. I had missed it before, because of my lower viewpoint.
That. Is. Awesome. Its really gaming heaven.
Its a real shame this simple mechanism that ensures different playstyles/ experiences because of literally different viewpoints is no more.
