thats a real shame, I think that the priest racial spells are a great way to help you make your mind up of which faction and race of priest you want to play, also its the one thing that sets you apart from other priests which is a good thing seeing as the character customization is quite limited. It would be so cool if other classes had this also.
One example I can think of would be to add one for warriors, say tauren warriors would get the ability to hit harder for a short period say 20 secs, 5 min cooldown and to balance gnome warriors would get the ability to hit more accuratly instead (same duration / cooldown). Of course other race warriors would get abilities too that was just an example.
When I saw the priest racial spells I imediatly thought "now theres something I have not seen in any MMOG I've played so far".
