First of all, I have to ask. Why are so many people afking urgents? There's been a minimum of 1 afk player per run in every urgent today. I get you've "done" this 100 times. You have a choice to just not screw over the other 11 people and sit it out.
That aside something needs to be added so we can just remove said offenders from our urgents. We are already undermaned and not like the get penilized for leaving the quest, anyways. Im not going to do all the work so they can get the rewards. But it's personalized! Leeches do not add anything thing to the group. Best to be rid of them.
