'Farm' parties are supposed to consist of people who feel comfortable with the entire fight and all of its mechanics, the most communication that should take is discussing how other people's groups cleared the fight before to prevent mistakes I.e. Everybody knowing their role. If a fight is beatable without VoiP's then that should be the benchmark of a 'farm' party, otherwise it frankly isn't one in the first place. But hey, that's what's currently so wrong about PF, people name theirs 'farm' parties in hopes of finding the best possible players when other people join expecting the same thing. People should quit searching for free carries and only join the PF's they are supposed to; learning (no to little exp), progression (exp up to a certain point/mechanic), kill (close to having cleared it, mostly familiar with each mechanic) and farm (enough clears and exp to be able to easily coordinate with players on the same level). I really don't get what's so difficult about that.
