Time limit to re-enter dungeons

[Richard]

Guess we will find out soon enough.
Bottom line is if is hard enough you NEED to be 50 to complete it, is end game.

If is great sp and it can be completed at 45, is leveling grounds.

No point to keep arguing without further information , everything else is just speculation.
dynamis was never a leveling ground, and for most key jobs you needed to be way above requirements.

I think the fact that the trash mobs are 10~15 levels above the party levels and the boss will likely be a Lv.60+ NM it will constitute as endgame - even when just speculating. Also:

Dungeons have officially replaced leves as the "spam this 600 times in a week" and then /slit your wrists at the thought of entering them.
