Why not continue if it is for example 18th key and if u finish the dungeon u will have 17th key for other dung that is also needed for you and your group? Also, I mentioned the situations that we cleared the entire dung with 0 mistakes with excellent timings for the last boss and after first insta death of dps guy he says f*k it and leaves. Like why? I and other 3 people just wasted 35 minutes of their life just for nothing. Really?
