Well, not exactly intentional, but not wholly objectionably either. It's certainly one case where the results from the system are a bit unexpected, but, as I mentioned in my post, I think having half-breeds sometimes come out with rather unexpected traits is a good thing. After all, gnomes and halflings were never really meant to breed together, so if strange things sometimes happen when they do, it shouldn't be a shock.
Yeah, I know, I mostly threw that in for completeness's sake. I figure if a DM decides some rare and inexplicable event leads to an Elan having a child, who am I to stop them?
