The last game I tried to PUG much was TSW (the original) and people rampantly spammed LFG tells with "speed run, must know fights " and this was a month or two post launch which is when I typically join games.
One day as a lark I posted something like "clueless group forming, will be resting often and no knowledge required "
I was bombarded with tells asking to join me and we didn't prevail that day but everyone had a good time and no one bitched about dying.
I quit right after that but if I ever go back to PUGs I might form my own guild for like minded folks.
Probably call it CDR, Clueless Dungeon Runners or something like that.
Could end up as one of the largest guilds in the game.
