Many months ago, when they added mentor and altered duty finder matching formula, they made it very difficult, if not impossible to assist friends in progress. I understand prioritizing mentor rouletters for joining in progress, but if there are none available it should pull from those who queue directly, instead the new formula does not prioritize joining in progress at all. When friends run into trouble and need reps, you can queue for that duty, with in progress checked, and duty finder will put you with a new group, or not place you at all. This means if you lose a tank of healer your going to be sitting around in a duty doing nothing, waiting forever till you have to abandon. It shouldn't be this way. You should still be able to queue in progress and be prioritized to join those over fresh groups and help you friends in struggling dutys. It absurd that you can select in progress, and your friends duty just sits there with an empty slot and duty finder refuses to offer it to you.
