I started the immensely long quest chain for the Sons of Hodir faction. Why am I skipping Zul'Drak and heading straight into Storm Peaks just for the Sons of Hodir? Because THEY are the ones that have shoulder enchants. If you aren't a Scribe, this is a MUST HAVE faction.
That being said, this quest chain is AWESOME. There is a quest that might be one of my favorite quests in the entire game. I won't spoil it, but it involves proto-drakes. A lot of them. And a harpoon. It's buggy, but it's still fun.
