I understand how the penalty works, what I don't understand is why it effects BOTH when you cannot queue for BOTH. Why do they treat them as one for the penalty but separate for queuing? That's what my post is about.

Regarding wasting time, we spent an hour in duty complete. It was 5/8 premade, with me being one of the 3 joining it solo. The premade group refused to abandon and would not vote kick their healer who afked for over 15m to "start dinner." They also thought it would be mildly entertaining to make the other 3 of us wait around and would not agree to dismiss us. They kept pulling the boss and dying on purpose, therefore wasting our time. I was left with options, wait until our instance expired or abandon the duty.

So, while you speculate as to my culpability, you refrain from addressing my original point.
