Since the discussion about Drakul brought up that the island is for dragons only, I'd like to see each race have its own private area too, complete with resources and properties only members of that race can own.
For gnomes, it could be the Rachival Research Institute.
For dryads, it could be a sacred grove.
For dwarves, it could be a special mine.
For fiends, it could be icy caverns.
For saris, it could be catnip fields.
For half-giants, it could be a mountain tarn.
For sslik, it could be the hatching beach.
For elves, it could be an enchanted forest.
For humans, it could be a farm.
For satyrs, it could be woodlands with a stream.
Each would be accessible by portal only, by members of the given race only. There would be a no-fly zone over it (red walls up around it). This would give each race the privacy and exclusivity to develop their own culture without interference by other races.
