It WAS 15 minutes in early 2.0, but people still abandoned parties because 15 minutes meant nothing to them until the devs doubled the timer. I also don't agree with giving people a free pass if they wipe a few times because it would either encourage people to be even more toxic if there's X wipes or people will become even lazier knowing if they screw up a few times, they can just leave without penalty and do it all over again in another party. It's getting rather silly seeing so many people trying their darndest putting in so much effort just to avoid a few minutes of sitting out of DF.
