I like to run dungeons casually; killing mobs, looting chests, and talking to NPC's. But these days you always get at least one group member who charges forward, pulls/avoids mobs, and triggering boss encounters while the group is still halfway towards the spot. Sometimes just arbitrarily making it a corpse run. They may just want to get set pieces asap, but it ruins the fun for players that want to enjoy the runs. I asked if adding these guys to ignore would keep me from grouping with them when using dungeon finder, but was told that's not the case. I REALLY think that should be the case, as well as some indication that when you are invited to a group someone you IGNORE is in it.
