But they're not the only orc clans, nor the only clan leaders, and if we just focus on them we're missing out on the potential of the lesser known clans. Clans like the Thunderlord, the Bladewind, the Rageroar and others, which were wiped out or otherwise not as important but which can rise to prominence in this new Iron Horde. Why should they concern us? Well, several reasons.
- They give us a chance to see a less monolithic side to the Iron Horde. Orc society was based entirely around the clan - it's about time we get to see this. Show us some clans. Give us a chance to observe how one goes about welding a nation out of them without the use of demonic magic and coercion.
- There's been a lot of discussion about the lack of representation of female characters in Warlords of Draenor. Since we can't just gender flip established lore figures, these lesser known clans provide a perfect opportunity to establish new characters and have them rise to prominence through their actions in the story. The Rageroar, for instance, are barely known - their only real appearance was in Cataclysm. We have no idea who their leader was back on Draenor - therefore, there's no good reason for it not to be a woman.
- Some of these clans defied the Old Horde of Ner'zhul and then Gul'dan. They could well defy this new Iron Horde as well, and it's simply better and more believable if we get to see some orcs preferring to keep to their older clan based way of life and rejecting new siege technology and all that the Iron Horde brings as being simply not orcish enough.
