@Possum (why, oh why can we not directly reply to a reply....)

I -really- wish that Blizzard wold write draenei as more complex-- they're certainly capable of it, and there are a few quests in their start zone and Outland that show that, even as the 'pure good' faction, they are capable of being somewhat dark. For example, in the short story 'Unbroken' they react to the mutation of the broken with fear and xenophobia, and for a long time exile people who were friends and family.

Note that the broken are, in fact, the few who survived the siege of Shattrath. They chose to stay in Shattrath and defend knowing they were very likely to die or worse, hoping the orcs would think that they were the last of the Draenei and not try to find the ones who had hidden in the Zangarmarsh and Nagrand. In other words, the broken are -heroes.- Even now, the broken seem to be treated as laborers in the Exodar, and not as normal citizens. For that matter, the draenei deliberately left children in Shattrath along with the volunteers, knowing they would be slaughtered, in order to let the orcs think they finished the draenei off and let the rest go into hiding. It's a logical choice, but I'm not sure if it's the 'good' one. Unfortunately, we don't see that somewhat alien mindset in-game. (Or the draenei in general in-game.)

The problem is, their 'hat' is being Good and Pure (and incapable of piloting.) Like gnomes and quirky technology, they rarely appear otherwise unless it's a plot point.

I RP my main-- a redemption-seeking draenei death knight who's trying to be normal and sometimes succeeding-- in a guild full of draenei RPers. We actually see a surprising amount of internal conflict, some of it driven by the fact that actually living up to the expectations of Draenic society is rather more difficult than it looks. However, they are-- admittedly-- often slice-of-life RP issues, and not the sort you would see addressed in a quest....
