I've been noticing a pretty big trend with about any Extreme mode that's been here to date. People after 1-3 tries do the following:

A) Ragequit and auto-leave without warning. Causes issues and breaks apart parties. Happens quite a lot.

B) Get mad at others for not doing X mechanic, or not pulling enough DPS/Heals/Hate. Possible loss of focus and could trip over something while ruminating on it.

C) Get back up and try again(getting rarer and rarer nowadays with PUG groups).

Most of the time it's either internal anger that they blame the group silently or vocally for not being able to do the fight. On release, there's a whole bunch of parties made to work on Nidhogg; but come 3-4 weeks later or a month they're all on farm. It's been the trend, which I understand why, but I'm unsure as to how many players step up to the challenge against the current end-game Extreme.

It's somewhat pitiful how people react and cause such vitriol at times.
