Time limit to re-enter dungeons

[Tadacho]

You are allotted 1 hour per run. How long it takes you is up to your party.

Ah fair enough. Even so, my argument still stands - if you're bothered about re-entering every 5 minutes, just don't do it! Impose a 24-hour restriction on yourself... People would only bitch if SE did that anyway. They can't win.
