Time limit to re-enter dungeons

[Misha]

You get feeling of accomplishment by beating a difficult content, not by giving it a cooldown.

a content with cooldown and no challenge will not gives u sense of accomplishment.

This is what alot of the naysayers don't get lol Cooldown adds NOTHING to the game but more grief or handholding for those that can't control themselves and act like they HAVE to clear the content cause other people are doing as such or because it allows em too lol @ all the people acting like this is FORCING you to play the dungeon back to back or that you have to cause other people decide to do it that way >.< Play at your own pace with your own friends in your own way, who cares how others play xD

Edit: Challenge or accomplishment or even longevity comes with content that is harder not more restricted^^ Let's just hope Yoshi was right about it being hard, otherwise doesn't matter either way :P
