I agree that the best reason to get the EBI is just to have a second breed location, however there is also a slight but real increase in your chances of getting epic/limited dragons when breeding there.

The people who test the limited and rare dragon combos for this wiki have done extensive testing (hundreds of tries per combo on both the island and the cave using hacked gems) and the results show a notible increase in numbers when the island is used.

Also Backflip have hinted in the description that it improves the odds and it is not in their best interest to lie about it, especially since a small increase of chance still barely impacts on the average users chances and won't reduce the number of gems people buy.
