This is starting to get pretty annoying from players who leave the moment the duty start or before it starts either due to the player not at the ilvl they expected it to be or don't expect it to be a speedrun. I know that ppl don't like it, but it should be a increase in the penalty for players who does that especially when it's already difficult to do dungeons at lower levels. Instead of 30 min there should be increase each time they continue to do so. 30 to 40 to 50 and so forth and the effect last the week. Not to make it permanent, but more of a testing ground to give players a second thought into joining duties. To leave the moment they enter dungeons that they don't like or that the players that they are with.
