Douches become more douches...
1. Entering a second depth, a player crafted the new weapon then told the rest something like "see you dimwits"
2. A player stayed at elevator for the whole time on Grasping Plateau, later he yawned and bored emoticon then logged off.
3. A player keep lying on the ground for the whole time, while "waiting" sigils thrown at his face.
4. A player refused to do anything useful beside tailing you for the whole journey of smashing and disrespecting their gravestones at Grasping Plateau.
etc etc etc...
Reminds me of the time when Kicking and Soloing didn't exist: When I was a Noob I joined a party, once we reached Depth 4, someone wouldn't let the party progress until we gave him all our crowns and he said he wouldn't let anyone progress unless we met his demands.
Left and never joined a party again until I was decently better. (IE: Pre Vanaduke, and even then people were still jerks. Who the heck asks the PARTY LEADER TO LEAVE SO THEY COULD INVITE THEIR FRIEND?)
This is what happens when people are like this. People like this exist in this game and it's just not right.
Most I would suggest is reporting them as it breaks the ToS. (For #2 at least, #1 can be reported for violent chat) There's a point where it's understandable and there's a point where it's just jerk-ish.
