I'd also like to see something similar done to the three Grand Companies, quests that tie into the lore of the organizations. Learn more about it's founding, it's former/current high ranked members and heroes, and seeing the general structure on how they work from the inside. Since we're pretty high in the ranks as it is, I could see this easily making it what gets you from rank to rank in the higher tiers. Heck, you could get rid of that seal cost for rank increases and replace it with something akin to reputation.
