I only leave if I need to because of life outside the game or if people leave and it doesn't look like the party will fill up again. Otherwise, I have no problem redoing fights over and over and over and over and over and over and over and over and over and over and over and over and over and over and over...again as long as the other people in the party want to.

The exception is if I'm the one causing the wipes. Then, depending on whether they're people I know or random or how I feel the other people are feeling, I may choose to leave before they kick me.
