Let's talk about the leaver penalty.

[LeoLupinos]

Got this after my first atempt on google "ffxiv duty penalty for leaving":

"The three strikes rule only applies to when you withdraw from queue.

The only ways to get out of an instance without the 30m penalty, is to leave when the party isn't full or get kicked. If someone else leaves, you're free to exit as long as nobody else joins to refill the party." Source

Please, May you use google next time before creating a 1-page-lasting-thread.
