I wonder about something... Are AK, Titan HM, Coil and all these other endgame dungeons not mentionning "one or more members of your party is new" at the beguining, when it's someone's first time?

I can't see how the team can ignore the fact that one membre likely doesn't know the fights when the game itself states it right from the start (that's in reply to the one mentionning people doing a speedrun without explaining anything nor pausing).
Same reason, I can't see how someone can expect to keep the lie when the game sells them out automatically...


Personally, if I always stop before the first boss battle and simply ask "Does everyone know the fight?" before stepping inside the room. Takes all of 2 seconds to type, and can save so much time (compared to finding out by wiping that some people had no idea what to do).
