Agree with the thoughts in this thread.

My thoughts:
The major flaw to me is there is no explanation (or lacking one) of why the guild leves are important. Like the intro scenes and story should emphasize the purpose of the Adventurers Guild and its role in Eorzea (each city little different maybe) and why you should be interested in it. Is the Adventurers Guild just a place where random NPCs hire mercenaries for odd tasks? That is what it seems like. Let's just say that is the case. At least they could have given you ranks and such so that you worked up the Guild to more challenging leves with access to gear/rewards for more challenging leves. Seems like a lot of missed/lost potential. However, I do think they can rectify it and have made some of the first steps (lower SP rewards etc).
