The leve system does open up the possability for some tweaks to the idea of redoing certain types of content. Randomly generated content would fit well into the leve system, since you would have access to a leve you can share with a group only one person needs to have the leve to get others in..
By R.G.C. I mean alterations to evisting areas and creatures to freshen up the location and the experiance for the duration of the quest, it would require something like what WoW has done with the phased content (can't remember what they call it hehe). The FFXIV devs have said that leve mobs will be for those on that particular leve only, so atuned areas and content isn't to big of a leap IMO.
I would make it some kind of token turn in like the BCNMs were to limit the wacky stuff and keep them from getting to confusing, keeping them to highend content would also be ideal I think.
So what do you think of the idea of randomly generated leves, How would you impliment something like this if at all?
