Hey guys, I have a question.

I always thought leaving a duty with a premade party doesn't result in a penalty.
We joined Ex roulette as a premade, but thanks to miscommunication of our party members, we ended up with two healers. I quickly left and wanted to queue up again (since you can't vote abandon until after 15 or something minutes have passed), but I was rewarded with a penalty.

Did my memories trick me or does Duty Finder give penalties for leaving premades too? Or is this something that's not supposed to happen?
