We're just going for the questions today.
Where are all the Draenei in the Kirin Tor Offensive Base camp. You'd think that in the time since wrath there'd be a few Draenei who are attuned with crystal energies in the kirin tor; or at the very least a commoner sitting around like the Dwarf, gnome, and Human.
There's an in-game reason, which is that for a while now the draenei have been trying to decide whether or not they should even stay on Azeroth. If you remember the Prophet's Lesson short story, the Exodar was repaired and the draenei had to decide whether or not they were going to remain on Azeroth or head out into the cosmos again. Ultimately they chose to remain, to prepare for the war between light and darkness that Velen foresees, but it was the big issue taking up most of their time.
However, I do think that it's kind of silly that we have blood elves, goblins, even worgen integrated more into the world than the draenei are. There's a draenei serving alongside the Kirin Tor forces (he gives quests in the Za'Tual area) but he doesn't even appear to be a mage. And yes, there's a draenei in the SI:7 forces that came to Pandaria, but I still feel like we could do with some more draenei out and involved in the world.
Hopefully the next expansion will give draenei some screen time. At present I'm seeing so many high elves I'm starting to wonder why they aren't a playable Alliance race.
