Priest Training and Report to Nasuun show as available quests on my dwarf priest.

Priest Training is a draenei exclusive quest that requires the completion of Replenishing the Healing Crystals. There is an alternate version of Replenishing the Healing Crystals for the other alliance races which I have completed. My guess is that Priest Training is incorrectly listed as a follow-up to the non-draenei version of Replenishing the Healing Crystals.

Report to Nasuun has an alternate version also. My character has completed neither of these and neither are available to it. It seems it is an optional pre-quest to Intercepting the Mana Cells and becomes unavailable if you start (or maybe complete?) Intercepting the Mana Cells.
