If it helps any, there's dumb players everywhere.
In another game, just now, I announced on the group-recruitment channel that I would like to do a dungeon, and I got an invite almost immediately, and joined a group with four or five other players. I said "What dungeon are we doing? I'm up for anything between Royal Mastogob and Snowfoux!" The team leader said "cats 'n rats." I said "That's not a dungeon." The team leader said "cats 'n rats" again.
It turns out he was 100 levels below me, and he didn't want to do any dungeons at all (In a game with a cap of level 200, I'm level 164, he was level 60-something in the endgame area, where the lowest-level dungeon is balanced for a team of level 120s and up).
No, he wanted to fight the minor in-town spawns (Wooly Bow Meows and Stunted Rats), with me doing most of the heavy lifting. I dropped that team immediately.
Yeah, it's a bit off-topic, but for me, "cats 'n rats" is going to be the new "kill skuls."
