I'm confused by some of the restrictions we have.

Considering how people manage to buy the wrong tomestone items and then complain to a GM about it, now the devs have to idiot proof everything, including doors.

That's what I'm saying though, there IS no possible bad outcome to opening a door so it is pointless to have the game ask if you really want to do it.
It makes sense for everything that has a possibly negative outcome to the player (like buying the wrong item and being unable to obtain the tomestones back, or losing Gil for teleporting to the wrong place, etc.).
But you simply don't HAVE that possibility with the doors, since opening them doesn't even start a battle with the opponents behind them.

It's not like everytime I use my chocobo whistle I get asked if I really wanna call my chocobo and mount it.
If there is no negative outcome, there is no reason to have a safety mechanism in between.
