While I agree with the OP's point that people need to be more flexible when joining PFs, most PFs nowadays list a strategy, so if you join one doing triangle strat and get mad that they don't want to adjust to circle or vice versa, that's on you... Otherwise I do agree that there are lots of inflexible people in PF. Had a Furor party fall apart because one person didn't like the MT's placement of markers, like really??

But just FYI, triangle is bad and ugly. (This post brought to you by the Circle Clan.)
