You might not want to invite a third player on Reddit if you are going to ignore them when they message you ~40 minutes later, and refusing to do anything other than farm the level 1 Earth cave trash mobs doesn't suggest much skill; neither does not knowing how the party/grouping system works "can't you join on me if we're friends (party is set to private)." Which is really funny because your group would be exactly 2/3 incompetent if anyone joined you.
