Pretty much against it, if were going to have race defining traits they should be made in a way to not hinder or advantage one race over another, which became a prominent issue back in FFXI.

Examples that wouldn't be groundbreaking:
-Certain Races are slightly stronger to certain elements.
-Slight speed bonuses depending on terrain. (IE: Wildwood Elzen would receive a speed bonus in the woods, Dunesfolk in desert areas, Sea Wolfs in costal areas, etc.) *Voided in instanced events.
-Slight idle heal bonus depending on terrain. *Voided in instanced events.
-Increased gathering bounty for your races home reigon. (Sea Wolves- Limsa, Wildwood- Grid, Dunesfolk- Uldah, etc.)

I guess most of the advantages listed would be more of a home turf advantage rather than a racial advantage, but still nothing about it's ground breaking albeit could be useful in the end.
