This won't help for ones that leave legitimately and eat the penalty...



On the other hand, if they eat the 30 minute penalty, well, I don't think anyone should be forced to stay. AFKing/DCing at start is just scummy.

Even if they don't say anything, if they AFK or DC at start, I would still try reporting it because GMs can probably see if this person makes a pattern of it or if it's just a one off. I looked at my character's files and AFAICT logs go all the way back to when the character first enters Eorzea.
