I would agree that there should be more rewards period for running dungeons. I ran each dungeon exactly once when I was leveling up, and the experience was worthless - and the gear wasn't worth it either. So, I used FATEs to supplement my main storyline questing. Nowhere near as exciting, but dungeons didn't give me seals or exp - why bother ever running them again?

I feel the same way about end game - why not have the bosses in The Praetorium or Castrum drop loot, or provide larger amounts of gil? Why not throw seals into the mix? I'm not looking forward to running them constantly just to attain gear to progress into coil. Dungeons feel like they are just sort of tacked on in this game, with barely any conceivable storyline in them until the final two and the rewards just aren't up to par.
