Time limit to re-enter dungeons

[Misha]

Guys before you start thinking you can do it 50 times a day, remember there may be some form of currency required to enter like BCNMs.

Exactly, not much is known now aside from the fact that you can run dungeons however you want, so if you work and don't have much time during the week can do a few runs in a row on a day off. Or if a friend invites/wants/needs you, you can just go ahead and do it with no worries^^ Especially useful if you have friends from all regions of the worlds so you don't have to coordinate specific times
