To me this sounds like a good thing. Alot of you are complaining that it is so short? Why?
To me if a person wants to camp out a dungeon to get all the virtual items for their character, more power to them! I don't have the time to camp a dungeon all day long. And if ppl can put forth the time to do so they should be rewarded by getting the items sooner than everybody else!

Personally when I only have 2hrs a weekday to put towards a game I don't want to only be able to play once and call it quits for the day.

This is about a fair of a way to split it.
What I would be more insterested about is will we be able to get in. With only 2 gungeons will there be a limit on the amount of instances that can be ran at one time. Most instances there is to control lag! If you have everybody in the game coming to do the same dungeons, it is unlikely we will be able to get in. :P

I would hope that the figure this out shortly after they launch it, or what would be totally awesome of they add in a queuing system before they launch.

That way you have to go to the physical location to enter the queue, maybe possibly pay to queue. (yes I know other games offer this service for free, but this is FF and SE here. You know how they work) Then once you are in the queue you don't have to wait around to get in to play!

You can go about your business and when your turn is up you get a pop up message that the instance is ready. You got 3mins to respond. If you say yes, you are teleported to the instance with your party members you listed in the queue!
Say you don't respond you are automatically entered in the next available queue. (this repeats 3 times). If you fail to respond 3 times you fall off the queue list altogether and have to go back to be enlisted again.
