Forum:Were the Highborne inbred?

So according to Timeline, if I'm understanding correctly, the Highborne had been holding themselves above other night elves since year -13500, and had been living isolated in exile since -10250. Did this cause inbreeding problems? If so, did outbreeding increase after the start of Burning Crusade in canon, to anything near the extent YouTube (where belf females seem to display affection to guys of every race except their own) and the average Horde /2 would have us believe? --Seahen (talk) 17:31, 5 August 2013 (UTC)
