Has way more pros than cons. Being able to get all around the world in no time at all, the ability to scout, the ability to hide in a place pretty much nobody else can get to, etc. As I said...I don't see that happening.

Is that all that's wrong with it?

How about limiting it to arials who are carrying (and, of course, wearing) no equipment or money, and limiting the effectiveness of "where" so that it only shows the "up in the air" location, and none of the areas below (which would tie into the issue of not being able to control what room you arrive in).

Now it's mostly of use just after you've died.

Maybe add a bit of lag after coming down, to make it a bit less useful for other purposes. After all, the scariest part of flying is landing.

But since this is purely based on flying, which in a sense is already an inherent, and not on not anything that's unique about the race -- such as their wings -- I'm not sure that I like it as an inherent.

Personally, I'd like to see something like a wing buffet which might be something like a weakened bash combined with dirt kick (three components which can succeed or fail independently: minor to moderate damage, moderate chance of throwing off balance, moderate chance of blinding). This should probably be affected by terrain differently from dirt kick.

That, and maybe occasionally having hand-to-hand damage reported as a "peck" rather than a "punch". (automatic skill, probably a different damage type but no other mechanical differences).
