Time limit to re-enter dungeons

[Dreadnought]

i read a handful of posts and saw some griping that i noticed didnt make sense

Utilizing content =/= finishing content in 1 week. Even your precious World of Warcraft is not this casual.

actually yes you can.
in both WoW and Rift you can spam dungeons immediately after one another. even the same ones. in WoW which ones you can spam are randomized but you non the less get the same ones. in Rift as far as i can tell they are not random, you pick and go-- i believe this will also work for FFXIV

also, i saw someone say dungeons as being a "new way of xping". in most MMOs questing is half of how people level.
the other half is done strictly through queueing and spamming dungeons. with the amount of mobs and the help of a group you are able to accumulate more XP overall even though XP per mob is less.

this whole system may be new to FFXI players, but its pretty archaic as far as most other MMOs.

also to note- most MMOs have harder versions of the same dungeons which cannot be repeated immediately, there is a 24 hour cool down. who is to say this is one of those types of dungeons and not one of the more "just for right now" type of dungeons? its difficulty? id only imagine future dungeons will only be harder.
