Please remove the lockout for leaving instances.

But guys, what if his cat really WAS on fire?

But seriously. This would cause much more harm than good. How often do you run into a 3/4 or 7/8 premade that acts like a group of jerks, compared to running into 1 guy that acts like a jerk (and would leave if there wasn't a penalty because his time is too precious). If you have to go because of a real life issue, its not like the lockout is harming you. And if you have to do something with your FC, being in a full premade bypasses the penalty.

And do you really want to overwhelm the GMs with (more) countless reports of someone leaving a dungeon for no reason? Additionally, if they did decide to impose a penalty on a case by case basis, the penalty would likely be huge.

At the end of the day, there is no smoke without fire. When a player enters a particular trial or dungeon (roulette aside), they generally want to complete it for a purpose. If they want to leave it's generally for a reason.
