Why is there even an argument. The player will dictate the speed at which he wants to do the run. To expect a stranger to follow your every orders is completely ****ing retarded.
This is where you meet halfway to at least finish the run. If a player cannot meet halfway or be reasonable, **** them.
Jesus, it always bugs me how antsy some player are about Brayflox HM.
TLR I really hate the community of FFXIV when it comes to Brayflox HM.
