The way I see it and I am probably wrong is that when the game is finished the easy way out of the Death Realm -- least walking, fewest obstacles -- will result in a racial spawn point, aquatic elves in the watery levels, klyros at the top and everyone else in between, for example. More difficult to access portals will provide better spawn points. So if I were to play what I expect my aquatic elf would rarely get to Hydlaa much less always spawn there. It just does not make sense to me that the Hydlaa Spawn point is OOC when it is all we have. This is what I am talking about but it isn't too important anyway.
See my nice tempest in this teacup?
